Manufacturing method of negative electrode material for lithium ion battery |
abstract |
The present invention provides a negative electrode material capable of obtaining a lithium ion battery having a large charge-discharge capacity and excellent charge-discharge cycle characteristics. In the present invention, the negative electrode material for lithium ion batteries is obtained by a method comprising the following steps: surface-treating carbon particles (B) containing graphite materials and the like with an oxidizing agent, followed by removing oxidant residues; (B) a step of modifying with a silane coupling agent; a step of connecting the modified carbon particles (B) and particles (A) with chemical bonds; The composite particles of (B) are subjected to a carbon coating step. |
