Title: CORE-SHELL COMPOSITE PARTICLES FOR ANODE MATERIALS OF LITHIUM ION BATTERIES
Abstract:
The invention relates to core-shell composite particles, the core being a porous, carbon-based matrix containing silicon particles and the shell being non-porous and being obtainable by the carbonization of one or more carbon precursors, the silicon particles having average particle sizes of 1 to 15 μm.
