Abstract:
The main object of the present invention is to provide a cathode active material capable of reducing the initial interface resistance against a solid electrolyte material. The present invention solves the above-mentioned problems by providing a cathode active material comprising a cathode active substance exhibiting strong basicity and a coat layer formed so as to cover the surface of the above-mentioned cathode active substance and provided with a polyanionic structural part exhibiting acidity.
