Title: CORE-SHELL-COMPOSITE PARTICLES FOR ANODE MATERIALS OF LITHIUM-ION BATTERIES
Abstract:
The invention relates to core-shell-composite particles, wherein the shell is carbon-based and non-porous and the core is a porous aggregate containing a plurality of silicon particles, carbon, and additional components, as applicable, wherein the silicon particles have average particle sizes (d50) of 0.5 to 5 μm and are contained in the core at ≥ 80 wt% relative to the total weight of the core-shell-composite particles.
