Title:
COMPOSITE ANODE MATERIAL INCLUDING SURFACE-STABILIZED ACTIVE MATERIAL PARTICLES AND METHODS OF MAKING SAME
Document Type and Number:
WIPO Patent Application WO/2019/027673
Kind Code:
A3
Abstract:
Composite anode materials and methods of making same, the anode materials including capsules including graphene, reduced graphene oxide, graphene oxide, or a combination thereof, and particles of an active material disposed inside of the capsules. The particles may each include a core and a buffer layer surrounding the core. The core may include crystalline silicon, and the buffer layer may include a silicon oxide, a lithium silicate, carbon, or a combination thereof.
