Abstract:

Silicon，which has high theoretical specific capacity（4212 mA·h·g^-1）as the anode material for lithium-ion batteries，was studied extensively.The research focused on the silicon cracking caused by the volume changs.The recent researches on silicon anode and compared the methods were summarized in this paper.
