▎ 摘 要
NOVELTY - Preparation of silicon-carbon negative electrode involves dispersing conductive agent (A) in dispersant solution to obtain mixed solution (A), mixing active particles, binder (A) and conductive agent (B) to obtain particles (A), placing particles (A) and binder (B) into solution (A) to obtain solution (B), mixing solution (B) with graphite and coating in a current collector. The conductive agent (A) is linear conductive agent and/or planar conductive agent. The conductive agent (B) is linear conductive agent. USE - Preparation of silicon-carbon negative electrode used for lithium ion battery (all claimed). ADVANTAGE - The method improves the long period cycle stability of the obtained silicon-carbon negative electrode, and the structure of the silicon carbon negative electrode is stable, and has long service life, and can effectively improve the performance of the battery.
