Silica anode material, preparation method of silica anode material and lithium ion battery |
| abstract |
The invention provides a silica negative electrode material, a preparation method of the silica negative electrode material and a lithium ion battery, wherein the silica negative electrode material comprises an inner core, a modification layer and a coating layer which are sequentially distributed from inside to outside; wherein, the inner core is silicon dioxide and nano silicon distributed in the silicon dioxide; the modified layer is lithium disilicate, silicon dioxide and nano silicon distributed in the lithium disilicate and the silicon dioxide; the coating layer is carbon. The silicon-oxygen cathode material provided by the invention is beneficial to improving the conductivity of the material and reducing the contact between the material and an electrolyte, so that the occurrence of side reactions is reduced, and the cycle stability of the silicon-oxygen cathode material is improved. |
