Document Type and Number:
WIPO Patent Application WO/2023/124913
Kind Code:
A1
Abstract:
A negative electrode active material, a preparation method therefor, and a secondary battery and an electric apparatus related thereto. The negative electrode active material comprises silicon monoxide particles, the bulk phase of the silicon monoxide particles containing conductive components therein. By means of distributing conductive components in the bulk phase of silicon monoxide, the conductivity of the material is enhanced, and the lithium intercalation and lithium de-intercalation capabilities of the material are improved, thereby helping to realize relatively high initial coulombic efficiency and relatively good quick-charging performance.
