Abstract Silicon oxide (SiO x ) material is gradually developing as a promising alternative to silicon due better trade‐off in terms of volume expansion and theoretical capacity. However, the low conductivity instability electrode–electrolyte interface caused by penetration fluorine anion (F − severely affect stability solid electrolyte interphase (SEI), ultimately leading capacity loss cycling instability. In this work, an “ionic fence” idea proposed, which effectively inhibits shuttle F promotes SEI. Based on this, dense orderly silicon‐based interconnected assembly covered TiN protective ionic fence designed using melt‐assembly technique nitridation strategy. After 1000 deep cycles, can be maintained at 431.7 mA h g −1 , average Coulombic efficiency reach 99.69% throughout process, even steady state after 2000 showing excellent electrochemical stability. Finite element analysis reveals that fence, stress management layer, constrains materials improves mechanical structural particles fully lithiated state, thus ensuring long‐term Selective design for has great universality development potential building stable electrode materials.

The ever increasing demand for a wide range of energy storage applications requires lithium ion batteries (LIBs) high and power densities. Traditional anode materials like graphite are unable to meet these requirements due their low theoretical capacity safety issues. In this context, alloy demonstrate great potential be used as propitious alternative realizing density LIBs, on account unique characteristics such exceptionally capacities, moderate operating potential, environmental benignity, safety, abundance. However, widespread use has been hindered by poor cycle life first irreversible capacity, which stem from adverse volume expansion consequent fracturing electrode. Tremendous research efforts have devoted ameliorating problems, fruitful results being reported. This review discusses the different alloy-based in major challenges experienced materials, recent progress made improving electrochemical performance.

Si‐based materials are taken into consideration as suitable anode for lithium‐ion (Li‐ion) batteries due to their high specific capacity. However, cycle life is limited volumetric changes during discharging and charging in Li‐ion battery (LIB). Silica (SiO 2 ) abundantly present nature, but standalone delivers moderate Li storage Commercially, graphite considered efficient LIB. The current research focuses on improving the performance of silica material achieve best capacity LIBs. Herein, core‐shell‐structured silica/porous carbon composite (50:50, wt%) synthesized using a hydrothermal method. shell porous not only covers core also provides very surface area ≈1057 m g −1 composite. acts an active half‐cell, which shows ≈642 mAh at 700 cycles 100 mA density retention ≈97%. helps uniform percolation electrolyte. It conducting path electrons further reduces diffusion time by producing more sites. core‐silica suppress that happen lithiation de‐lithiation process. Due these advantages, consistent stable cycling over large number cycles.
