Method for making lithium ion battery anode active material |
abstract |
A method for making a lithium ion battery anode active material comprising: providing silicon particles and a silane coupling agent, wherein the silane coupling agent comprises a hydrolysable functional group and an organic functional group; mixing the silicon particles and the silane coupling agent in water to obtain a first mixture; adding a monomer or oligomer to the first mixture to obtain a second mixture, the surfaces of the silicon particles being coated with a polymer layer by in situ polymerization method to obtain silicon polymer composite material, the monomer or the oligomer reacting with the organic functional group of the silane coupling agent in a polymerization, thereby a generated polymer layer being chemically grafted on the surfaces of the silicon particles; and heating the silicon polymer composite material to carbonize the polymer layer to form a carbon layer coated on the surfaces of the silicon particles. |
