COMPOSITE POSITIVE ELECTRODE ACTIVE MATERIAL, ALL SOLID-STATE BATTERY, AND METHODS FOR MANUFACTURE THEREOF |
摘要 |
A composite positive electrode active material includes: a positive electrode active material which includes a transition metal; and a reaction suppressor which is formed so as to cover a surface of the positive electrode active material, and which is made of a polyanion structure-containing compound having a cation moiety composed of a metal atom that becomes a conducting ion and having a polyanion structural moiety composed of a center atom that is covalently bonded to a plurality of oxygen atoms. A transition metal-reducing layer which has self-assembled on the surface of the positive electrode active material in contact with the reaction suppressor owing to reaction of the transition metal with the polyanion structure-containing compound, has a thickness of 10 nm or less.
