Abstract
A main object of the present invention is to provide a method for producing a cathode active material for a solid state battery, which is capable of reducing resistance. The present invention solves the problem by providing a method for producing a cathode active material for a solid state battery comprising steps of: a coating step of coating a coating material represented by LiPO(2≤x≤4, 3≤y≤5) on a surface of a cathode active material containing an Ni element and being an oxide by using a sputtering method; and a heat-treating step of forming a coating portion in such a manner that the cathode active material coated with the coating material is heat-treated within a range of 400° C. to 650° C. to diffuse the Ni element into the coating material.
