Research Progress in Silicon Based Anode Materials for Lithium-ion Batteries

Due to its high capacity,silicon based anode materials have been widely studied in recent years.The insertion/interinsertion lithium-ion principle of silicon anode for lithium-ion battery is mainly analyzed,the latest alleviation methods of cracking and crushing of the silicon are reviewed,and the shortcoming of these methods is also pre-sented.With the advantage of high conductivity,high elastic,porous,high stability,polypyrrole compouded with silicon will be the most promising developing direction to improve the cycle stability of silicon-based anode materials in lithium-ion battery.
