METHOD FOR PRODUCING ACTIVE MATERIAL COMPOSITE PARTICLES |
| 摘要 |
An object of the present invention is to provide a method for producing active material composite particles having a dense coating layer. In the present invention, the above object is achieved by providing a method for producing an active material composite particle, the method comprising steps of: a coating step of coating a surface of an active material with a precursor solution of a Li ion conductive oxide to form a precursor layer; a heat treatment step of performing heat treatment on the precursor layer to form a coating layer comprising the Li ion conductive oxide; and a compression shearing treatment step of performing compression shearing treatment on the coating layer. |
