Document Type and Number:
WIPO Patent Application WO/2023/210866
Kind Code:
A1
Abstract:
The present invention relates to a silicon anode material for a lithium ion secondary battery, and may provide a silicon anode material, for a lithium ion secondary battery, comprising a plate-shaped silicon complex produced using plate-shaped silicon formed from waste silicon kerf, wherein the plate-shaped silicon complex comprises: plate-shaped silicon particles formed by crushing plate-shaped silicon and having an apparent density of 0.1-0.4g/cm3; an oxide film formed by oxidizing the surface of the plate-shaped silicon particles; and a carbon coating film formed by coating conductive carbon on the exterior of the plate-shaped silicon particles so as to cover the oxide film.
