STRESS-BUFFERING SILICON-CONTAINING COMPOSITE PARTICLE FOR A BATTERY ANODE MATERIAL

摘要

A stress-buffering silicon-containing composite particle for a battery anode material, includes a stress-buffering particle having a Young's modulus greater than 100 GPa, a binder, and a silicon-containing shell surrounding and bonded to the stress - buffering particle through the binder. The siIicon-containing shell has a plurality of silicon flakes that are randomly stacked and that are bonded to one another through the binder to form a porous structure.
