| titleOfInvention | The preparation method of lithium ion battery anode active material |
| abstract | The present invention relates to a kind of preparation method of lithium ion battery anode active material, comprise the following steps: provide silicon grain and silane coupler, described silane coupler has hydrolyzable functional group and organo-functional group; In water, mix described silicon grain and silane coupler formation one first mixed liquor, also chemical graft is surperficial to described silicon grain in the hydrolyzable functional group hydrolysis of described silane coupler; Polymer monomer or oligomer formation one second mixed liquor is added in this first mixed liquor, utilize the method for in-situ polymerization at described silicon grain Surface coating one polymeric layer, thus form a silicon polymer composite material, described polymer monomer or oligomer are while polymerization reaction take place, react with the organo-functional group of described silane coupler, thus make the polymeric layer chemical graft of generation to described silicon grain surface; And silicon polymer composite material described in heat treatment, make described polymeric layer carbonization form a carbon-coating and be coated on described silicon grain surface, thus form a Si-C composite material. |
