We demonstrate a fully integrated eight-channel dense wavelength-division multiplexing silicon photonic transceiver supporting 200-Gbps per-channel PAM4 operation,enabling a total chip-to-chip data rate of 1.6 Tbps.The transmitter employs compact single-bus microring modulators,whereas the receiver adopts a polarization diversity architecture based on cascaded dual-ring filters and integrates a bidirectionally incident photodetector,maintaining stable performance under arbitrary input polarization.A unified multichannel thermo-optic feedback architecture is implemented at both the transmitter and receiver,enabling cooperative link-level wavelength alignment without pre-calibration.This multi-channel parallel control scheme reduces wavelength locking time by~30×while achieving fine wavelength-tracking accuracy of 2.74 pm with negligible thermal overhead.Comprehensive device-and system-level experiments validate the robustness and scalability of the proposed architecture.We uniquely address the critical bottlenecks of high polarization sensitivity and latency in wavelength alignment through a highly integrated silicon photonic architecture.By implementing polarization-splitting grating couplers and synchronized wavelengthlocking schemes,we provide a transformative solution for high-density co-packaged optics.Our approach significantly reduces system footprint,enhances operational reliability,and improves power efficiency,thereby bridging the gap between laboratory demonstrations and practical 1.6-Tbps scale chip-to-chip interconnects. 展开更多

Intense chemical weathering in tropical regions produces soils characterized by silicon(Si)depletion and iron and aluminum oxide accumulation,leading to soil degradation.Consequently,Si cycling is of paramount importance in tropical regions.This review summarizes the key processes of the terrestrial Si biogeochemical cycle in tropical areas and underscores its biogeochemical significance in ecosystems.Runoff outputs constitute the dominant mechanism of Si depletion in tropical soils.However,the combined effects of dissolved Si(DSi)retention by highly weathered soil and Si uptake by vegetation attenuate desilication rates in these ecosystems.Tropical soils exhibit limited quantities of weatherable minerals,resulting in soil solution with low concentrations of DSi.Consequently,the primary sources of available Si are atmospheric dust inputs from distant sources and biogenic silica originating from plants.Irrigation,application of Si fertilizers,crop harvesting,and corresponding Si exports significantly impact soil Si cycling within agroecosystems.Therefore,soil Si cycling in tropical regions is different from that in other climatic zones.However,there are still many knowledge gaps within contemporary research.We propose to delve into several perspectives,including the exploration of the processes,fluxes,rates,related factors,and mechanisms associated with Si cycling in tropical regions.Comprehensive research from these perspectives would significantly enhance the understanding of pedogenesis and soil evolution and provide valuable insights for guiding the sustainable management of tropical soils. 展开更多

With the development of electronic components towards high frequency,high efficiency,and miniaturization,the demand for non-oriented silicon steel ultra-thin ribbons is increasing,which were usually prepared by multi-pass rolling with complex processes and high cost.The ultra-thin non-oriented silicon steel ribbons with silicon content of 2–4.5 wt.%Si were prepared with the planar flow casting technology,and the microstructure and properties of ribbons were investigated.The results showed that as the silicon content increased,the grain size of the as-cast ribbons gradually decreased,and the dislocation density and internal stress were higher.The proportion of{100}oriented grains gradually increased from 29.3 to 37.3%,and the ratio of{110}and{111}oriented grains decreased.Meanwhile,the magnetic induction B50 showed a decline trend from 1.62 to 1.45 T with the increase in silicon content,while the iron loss P1.0/400 increased from 20.61 to 66.65 W/kg.This may be related to the silicon content affecting the wettability of melt and the wheel,thereby affecting the cooling capacity.The grains grew significantly after annealing,the internal stress was released and dislocations were eliminated.All this greatly improved the magnetic properties and decreased the hardness.B50 of ribbons with 2 wt.%Si reached 1.66 T and P1.0/400 of ribbons with 4.5 wt.%Si was reduced to 13.40 W/kg.The percentage of{110}fiber grains increased obviously while{100}fiber grains decreased slightly after heat treatment. 展开更多

The availability of dissolved silicon(DSi)relative to dissolved phosphorus(DP)regulates the dominance of siliceous phytoplankton in eutrophic waters,yet the redox controls on DSi internal loading from natural sediments remain uncertain.We incubated surficial sediments in ten parallel flow-through columns to disentangle Fe-P-Si interactions under alternating oxic and anoxic overlying waters.Columns containing 10 cm of sediment received anoxic influents with different combinations of Fe(II),DSi,and DP delivered through the bottom port using a peristaltic pump,while the effluent were monitored;post-experiment sediments were characterized using buffered ascorbatecitrate(BAC)and 1 mol/L NaOH extractions.Under oxic conditions,more than 90%of inflow Fe(II)was retained in the upper 1 cm of sediment,enriching BAC-extractable Fe and P by up to 40%relative to initial values.Transition to anoxia caused reductive dissolution of these phases,leading to Fe release of up to 193±26μmol/L and DP peaks of 160±30μmol/L in the overlying water.In contrast,DSi exhibited neither measurable retention during oxia nor systematic increases under anoxia,with effluent concentrations consistently exceeding influent levels by 20%-50%,indicating steady internal production.Mass-balance calculations show that DSi fluxes(20-40μmol/d)were dominated by continuous dissolution of amorphous silica,while elevated DP suppressed Fe-Si co-precipitation via competitive sorption on Fe(III)solids.We conclude that the interplay among porewater DP and DSi production rates,along with the pool of reactive iron,governs the extent to which internal Si release responds to redox variations. 展开更多

The rapid expansion of the photovoltaic industry has generated heavily oxidized waste silicon(wSi),which hinders efficient recycling owing to its small particle size and uncontrolled surface oxidation.This study introduces a molten salt electrochemical strategy for converting photovoltaic wSi into NiSi2-silicon nanorods(NiSi2-SiNRs)as high-performance anode materials for lithium-ion batteries.A stable oxidized passivation layer is formed on the wSi surface via controlled oxidation,and further in situ generated highly active NiSi2 droplets.The molten salt electric field modulates the surface energy of silicon,while particle integration drives localized directional growth,enabling the self-assembly of NiSi2-SiNRs composites.These NiSi2-SiNRs anodes exhibit rapid ion transport and effective strain buffering.The high aspect ratio of SiNRs and the presence of retained NiSi2 facilitate both longitudinal and transverse Li+ diffusion.Owing to their robust structural design,the NiSi2-SiNRs anode achieves an excellent initial Coulombic efficiency of 91.61%and retains 72.99%of its capacity after 800 cycles at 2 A·g−1.This study establishes a model system for investigating silicide/silicon interfaces in molten salt electrochemical synthesis and provides an effective strategy for upcycling photovoltaic wSi into high-performance lithium-ion battery anodes. 展开更多

Silicon possesses a high theoretical capacity,making it a potential contender for lithium-ion battery(LIB)anodes.Nonetheless,its practical usage is challenged by low electrical conductivity and significant volume expansion during cycling.Here,we synthesized a novel silicon/carbon(Si/C)anode doped with ZnO via a template-derived method and high-temperature carbonization.The carbon structure,originated from metal-organic frameworks(MOFs)and ZnO doping,substantially enhanced the electrochemical properties of the composite material.It exhibited an initial capacity of 2100.3 mA h g-1at a current density of 0.2 A g-1and demonstrated excellent capacity retention over successive cycles.Moreover,the composite material displayed superior rate performance at higher current densities of 2 A g-1and 3 A g-1.To address the low initial Coulombic efficiency(ICE)of siliconbased materials,we adopted a direct contact prelithiation approach and optimized the lithiation process by controlling the prelithiation time.After 30 min of prelithiation,the ICE reached 97.9%,thereby reducing the initial irreversible capacity loss(ICL)and realizing stable discharge-charge in subsequent cycles.This rational design provides valuable insights for achieving high-performance silicon anode. 展开更多

The electromagnetic wave absorption of silicon carbide nanowires is improved by their uniform and diverse cross-structures.This study introduces a sustainable and high value-added method for synthesizing silicon carbide nanowires using lignite and waste silicon powder as raw materials through carbothermal reduction.The staggered structure of nanowires promotes the creation of interfacial polarization,impedance matching,and multiple loss mechanisms,leading to enhanced electromagnetic absorption performance.The silicon carbide nanowires demonstrate outstanding electromagnetic absorption capabilities with the minimum reflection loss of-48.09 d B at10.08 GHz and an effective absorption bandwidth(the reflection loss less than-10 d B)ranging from 8.54 to 16.68 GHz with a thickness of 2.17 mm.This research presents an innovative approach for utilizing solid waste in an environmentally friendly manner to produce broadband silicon carbide composite absorbers. 展开更多

AIM:To investigate the effects of shortening the duration of silicone oil tamponade on retinal structure and function in patients undergoing silicone oil removal(SOR)after surgery for primary rhegmatogenous retinal detachment(RRD).METHODS:A total of 58 eligible patients were enrolled and randomly assigned to two groups based on tamponade duration:the short-term group(30-45d)and the conventional group(≥90d).Comprehensive evaluations were performed before and after SOR,including slitlamp examination,best-corrected visual acuity(BCVA)measurement,intraocular pressure(IOP)testing,optical coherence tomography(OCT),optical coherence tomography angiography(OCTA),microperimetry,electroretinography(ERG),and visual evoked potential(VEP)assessment.RESULTS:A total of 33 patients(23 males and 10 females;33 eyes)were enrolled in the short-term SO tamponade group with mean age of 52.45±9.35y,and 25 patients(15 males and 10 females;25 eyes)were enrolled in the conventional SO tamponade group with mean age of 50.80±12.06y.Compared with the conventional group,the short-term silicone oil tamponade group had a significantly lower incidence of silicone oil emulsification and cataract progression,with no significant difference in retinal reattachment success rate.Structurally,short-term tamponade was associated with increased thickness of the retinal ganglion cell layer(RGCL)in the nasal and superior macular regions and improved recovery of superficial retinal vascular density in these areas.Functionally,the shortterm group showed better BCVA and retinal sensitivity both before and 1mo after SOR;additionally,the P100 amplitude in VEP tests was significantly increased in this group.CONCLUSION:Shortening the duration of silicone oil tamponade effectively reduces damage to retinal structure and function without compromising the success rate of retinal reattachment in patients with primary RRD. 展开更多

The interfacial stress between silicon bottom cell and perovskite top cell remains a critical challenge for flexible perovskite/silicon tandem solar cells,leading to interfacial delamination and device degradation.In this work,the effect of the thickness and pyramid size on mechanical properties of silicon wafers are investigated,demonstrating that thinner wafers and smaller pyramids significantly enhance the flexural strength of thin silicon wafers by mitigating stress concentration effects.Based on these findings,a synergistic optimization strategy is proposed that employs precise wet-etching control to fabricate small-sized,high-density,uniform pyramids on 55μm silicon wafers for efficient and flexible perovskite/silicon tandem solar cells.By optimizing the texturing duration,this approach simultaneously enhances the minority carrier lifetime(τ)and achieves an excellent implied open-circuit voltage(iVoc).Furthermore,the uniform submicron-scale pyramid structure promotes high-quality perovskite film formation and improves interfacial contact properties.As a proof of concept,monolithic flexible perovskite/silicon tandem devices fabricated on such uniformly textured pyramids delivered a power conversion efficiency(PCE)of 30.04%.These devices promise for low-cost,lightweight and flexible photovoltaic applications. 展开更多

The magnetic properties of non-oriented silicon steel are affected by the composition and morphology of inclusions in the steel.It is necessary to minimize the number of inclusions and modify the inclusions during the manufacturing process.Rare earth modification of the non-oriented silicon steel is a common practice in steelmaking industry.At present,there is still insufficient research on the properties of rare earth alloys themselves,such as phase composition,inclusions in alloys,and the influence of alloy impurities on inclusions in non-oriented silicon steel.In this paper,the phase composition of Fe-RE-Si alloy was analyzed by X-ray diffraction(XRD)and electron probe microanalysis(EPMA).The inclusions in Fe-RE-Si alloy were analyzed by electrolytic extraction and scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS)methods.Subsequently,non-oriented silicon steel was melted in a high-temperature tubular resistance furnace and the Fe-RE-Si alloy was added for rare earth treatment.The evolution of inclusions in silicon steel after Fe-RE-Si alloy treatment was studied by thermodynamic calculation and SEM-EDS analysis.The results demonstrate that the Fe-RE-Si alloy is made up of two phases,i.e.,the Fe-Si phase and the Ce-Si phase.The inclusions in the alloy are predominately Al-Fe intermetallic compounds and oxide inclusions.The effect of the Fe-RE-Si alloy on the size,morphology and composition of inclusions in non-oriented silicon steel was investigated through high-temperature melting experiments and thermodynamic calculations.The results of experiments show that after treatment with Fe-RE-Si alloy,the rare earth inclusions in non-oriented silicon steel are mainly AlN-RE2O2S composite inclusions,a small amount of AlN-RES and AlN-REAlO3 composite inclusions.The modification sequence of rare earth inclusions in heat A(with a rare earth content of 0.0017 wt%)is as follows:RES/RE2O2S→RE2O2S/REAlO3.Besides,the modification sequence in heat B(with a rare earth content of 0.0119 wt%)is as follows:RE2O3/RE2O2S→RES/RE2O2S.When the rare earth content increases from 0.0017 wt%to 0.0119 wt%,the type of rare earth inclusions changes from RE2O2S/REAlO3 to RES/RE2O2S.The average size of inclusions in two heats increases slightly in 30 min after the addition of Fe-RE-Si alloy.The average size of inclusions in heat A and heat B increases from 1.89 to 2.59μm,and from 1.93 to 2.6μm,respectively.The average size of inclusions in the furnace cooling samples of heat A is larger than that of heat B.In both heats,after the addition of Fe-RE-Si alloy,the proportion of inclusions with the size of 0-2μm decreases and the proportion of inclusions with the size of 2-5μm increases.The effect of rare earth elements coarsening inclusions is significant.By calculating Gibbs free energy of the rare earth inclusions and the phase stability diagram,it is found that the thermodynamic stable inclusions in both heats are RE2O2S. 展开更多

Spartina alterniflora is one of the most widespread invasive plants globally,with particularly rapid expansion in coastal wetlands of China,posing a severe threat to the structure and function of native ecosystems.Ecological stoichiometry serves as a fundamental theoretical framework for understanding its invasion mechanisms and informing ecological restoration,especially regarding its demand for silicon(Si)and interactions with carbon(C),nitrogen(N),and phosphorus(P).In the present study,sediment samples were collected from S.alterniflora habitats(SA),Phragmites australis habitats(PA),and mudflat habitats(MF)to quantify the concentrations and stoichiometric characteristics of various Si,C,N,and P fractions.The results demonstrated that compared to MF and PA,the invasion of S.alterniflora significantly increased the contents of bioavailable silicon(ASi)by 1.3–1.4 times,reaching up to 347.5 mg/kg in 0–40 cm surface sediments.Similarly,total carbon(TC)and total nitrogen(TN)increased by 1.2–1.4 times and 1.5–2.1times,respectively,while total organic carbon(TOC)and dissolved organic carbon(DOC)were elevated by 1.7–3.0times and 1.7–2.2 times in the 0–40 cm sediment layer.In contrast,bioavailable phosphorus(AP)markedly declined,with SA sediments containing only 15%–64%of the AP levels observed in PA and MF habitats across the 0–100 cm sediment.In SA sediments,ASi exhibited a significant positive correlation with C,N,P,and their stoichiometric ratios(C/N,C/P,N/P).These findings indicated that the invasion of S.alterniflora modified sediment physicochemical properties by enhancing Si availability and restructuring the C,N,and P stoichiometric characteristics,thereby creating a sediment condition favorable for its proliferation,and amplifying its ecological invasiveness. 展开更多

Micro-sized silicon(mSi)anodes offer high capacity for next-generation lithium-ion batteries but suffer from severe volume changes,causing unstable interphases and poor cycling.Traditional electrolytes derive unstable electrolyte/electrolyte interphases,and flammable solvents pose safety risks.Here,we introduce a non-flammable molten salt electrolyte,which consists of lithium bis(fluorosulfonyl)imide,potassium bis(fluorosulfonyl)amide,and cesium bis(fluorosulfonyl)imide in a mole ratio of 0.3:0.35:0.35(noted as Li0.3K0.35Cs0.35FSA),that forms an inorganic interphase on mSi,stabilizing the electrode/electrolyte interface.Computational and experimental insights elucidate the FSA-anion decomposition-derived SEI predominantly of LiF,Li3N,Li2O,and Li2S,which exhibits mechanical resilience and low interfacial resistance,effectively accommodating the significant volume expansion of silicon during lithiation/delithiation.As a result,the Li||mSi half-cell achieves 60.7%capacity retention after 100 cycles with 99.5%average Coulombic efficiency.Overall,the Li0.3K0.35Cs0.35FSA electrolyte eliminates flammability concerns while enabling robust cycling performance.This work demonstrates a safe,high-energy battery system by coupling mSi anodes with stable molten salt electrolytes,addressing both interfacial instability and safety challenges in mSi-based lithium-ion batteries. 展开更多

To address the limitations of traditional silicone hydrogel contact lenses in wettability and drug release,an innovative approach was proposed by incorporating polyethylene glycol(PEG)and sodium hyaluronate(SH)into these lenses.Aminoalkyl-terminated polydimethylsiloxane(KF8010)was reacted with glycidyl methacrylate(GMA)to synthesize GKF8010,which was then mixed with methacryloxymethyltris(trimethylsiloxy)silane(TRIS),N,N-Dimethylaniline(DMA),and PEG400 to fabricate PEG-modified silicone hydrogel contact lenses(PEG-SCL)via UV molding.Unmodified lenses(SCL)were served as controls.The effects of PEG modification on lens properties,including water content,wettability,and optical clarity,and SH loading efficiency and drug release were evaluated.Additionally,the protein adsorption and biocompatibility of the lenses with human umbilical vein endothelial cells(HUVECs)were assessed.Results indicated that PEGmodified lenses exhibited superior water content,reduced protein adsorption,enhanced SH loading capacity and controlled release profiles,highlighting their potential for treating dry eye syndrome. 展开更多

Transverse thickness difference is a key indicator for evaluating the quality of cold-rolled silicon steel products,jointly determined by hot-rolled silicon steel data and cold rolling process parameters.However,there are“process barriers”and“data islands”between different production lines,resulting in low accuracy and poor interpretability.In addition,the transverse thickness difference mainly relies on manual sampling measurement.The lag and uncertainty of the measurement results lead to a lack of effective online control methods.To overcome this,a cold-rolled silicon steel transverse thickness difference control framework based on interpretable machine learning is proposed.First,a hot-cold rolling cross-process data platform is established to match and integrate multivariate data from different production lines,providing a data foundation.Then,an RUN-HLSSVM-AdaBoost model prediction model combining Runge-Kutta algorithm optimized hybrid kernel least squares support vector machine and AdaBoost ensemble modeling method is established.Afterward,the adaptive bandwidth kernel density estimation improved by local weighting strategy is used to construct a prediction interval,which characterizes the uncertainty of the prediction results.SHAPley Additive exPlanations interpretable method is used to break the“black box”limitation and reveal the influence of hot and cold rolling parameters on the transverse thickness difference,and finally,an online control strategy is proposed.Industrial experiments have verified the effectiveness of the above framework,and the transverse thickness difference has been significantly improved,which provides a new paradigm for solving the problem of online control of transverse thickness difference of cold-rolled silicon steel. 展开更多

Silicon(Si)anodes offer an ultrahigh theoretical capacity but face two major barriers to commercialization:severe structural degradation caused by significant volume changes and sluggish ion transport kinetics due to the discontinuous ionic conductance of conventional binders.To address these challenges,we develop a fully integrated Si anode using sulfonated graphene(SG)as a dual-functional ion-conductive and mechanical reinforcing framework within a conventional carboxymethyl cellulose/styrene-butadiene rubber(CMC/SBR)binder.Thermally activated reactions during electrode fabrication establish covalent sulfonate ester bonds between SG and CMC,elastic carboxylate crosslinks between SBR and CMC,and chemical anchoring between the binders and Si particles,which are all further reinforced by hydrogen bonding.This multi-bonding network not only dissipates mechanical stress and maintains electronic connectivity via embedded C65 carbon but also significantly enhances Li+transport through high intrinsic ionic conductivity of SG,facilitating the formation of a stable solid electrolyte interphase(SEI).The resulting Si@CMC/SBR/SG anode delivers a high initial capacity of 3513.2 mAh g-1and retains 77%capacity after 500 cycles at 2 A g-1.It achieves 762 mAh g-1at 4 A g-1and practical areal capacities exceeding 4 mAh cm-2.Full-cell tests with NCM811 cathodes confirm 86.2%capacity retention after 100 cycles.This work demonstrates a pragmatic and scalable integration paradigm for durable,high-energy-density Si anodes. 展开更多

To improve the ablation resistance of C/C composite at temperatures exceeding 2000℃,a(Hf-Zr)C-SiC Ultra-High Temperature Ceramic(UHTC)coating was prepared by Polymer Derived Ceramics(PDCs)and Gaseous Silicon Infiltration(GSI).The linear ablation rate of the coated C/C composites was as low as 0.27μm/s,maintaining a level as low as 10-4mm/s.This low Rl is attributed to the formation of a well-bonded double-layered oxide scale with high thermal stability,consisting of an exterior SiO2glass layer and an interior Hf-Zr-Si-O complex oxide layer.Meanwhile,the dissipation of the residual Si and the C phases relieves heat accumulation,ensuring that the recorded surface temperature remains below 2000℃,thereby enhancing the ablation resistance.Additionally,a cyclic evolution of linear ablation rate was found,due to the alternating dominant role of oxidation and mechanical denudation on the coating during ablation.This study provides theoretical and experimental support for the long-term anti-ablation design of highly dense UHTC coatings. 展开更多

Unlocking the full potential of integrated photonics requires versatile,multi-functional devices that can adapt to diverse application demands.However,confronting this challenge with conventional singlefunction resonators often results in cumbersome system designs.We present an elegant solution:a versatile and reconfigurable dual-polarization Si3N4microresonator that represents a new perspective in on-chip photonic designs.Our device can be dynamically reconfigured into three distinct topologies:a Möbius-like microcavity,a Fabry-Pérot resonator,and a microring resonator.This unprecedented functionality is enabled by a tunable balanced Mach-Zehnder interferometer that facilitates controllable mutual mode coupling of counterpropagating light using a single control knob.We experimentally demonstrate that the device not only supports polarization-diverse operation on a compact footprint but also gives rise to a wide variety of physical phenomena,including a standing wave cavity,a traveling wave cavity,free spectral range multiplication,and the photonic pinning effect.These behaviors are accurately modeled using the transfer matrix method and intuitively explained by the temporal coupled-mode theory.Our results underscore the potential for a chip-scale platform to realize reconfigurable reconstructive spectrometers and on-chip synthetic dimensions for topological physics. 展开更多

Squeezed light is a fundamental resource for a broad spectrum of quantum technologies,including precision metrology,secure communication,and quantum simulation and computing.The integration of squeezed-light sources with photonic circuits presents a transformative approach—not only offering compactness,stability,and scalability,but also enabling seamless high-fidelity on-chip generation,manipulation,and processing of quantum states without being hampered by inter-component quantum decoherence arising from loss and noise.In this work,we report the experimental generation of a two-mode squeezed vacuum state on a thin-film silicon-nitride photonic integrated circuit with normal group velocity dispersion of 6.3×105fs2∕m.Quadrature squeezing of-2.1 dB±0.09 dB and anti-squeezing of 7.1 dB±0.04 dB are directly measured.To fully understand the dynamics of the quantum process,a comprehensive theoretical model is developed to capture the squeezing performance,showing excellent agreement with experimental results.Our findings highlight the potential of the thin-film silicon nitride platform that capitalizes on fully foundry-compatible fabrication technologies to advance robust,large-scale,and manufacturing-ready quantum information processing systems. 展开更多

High-capacity silicon anodes hold great promise for safe and energy-dense all-solid-state lithium batteries(ASSLBs),yet their practical application is hindered by interfacial degradation and mechanical fracture,which severely limit their cycle life.Herein,we unravel the particle-size-dependent electro-chemo-mechanical failure mechanisms of Si anodes in sulfide-based ASSLBs.The micro-sized Si(μm-Si)anode exhibits favorable initial Coulombic efficiency(ICE,79.15%)and reversible capacity(2260.5 mAh g-1)but succumbs to progressive particle fracture under prolonged cycling due to cumulative mechanical stress from large volume swings.By contrast,the nano-sized Si(nm-Si)anode suffers from severe interfacial side reactions and irreversible volume expansion due to its larger specific area and dense electrode structure,resulting in lower initial performance(ICE of 72.21%,1372.7 mAh g-1).In subsequent cycles,the nm-Si anode experiences continuous interfacial side reactions,leading to substantial accumulation of interfacial decomposition byproducts and sustained capacity decay.These contrasting failure pathways establish electro-chemo-mechanical coupling as the governing prin-ciple and provide a particle-size-dependent design framework for high-performance Si-based ASSLBs. 展开更多
