Lithium solid state battery

Abstract

The problem of the present invention is to provide a lithium solid state battery in which reaction resistance is reduced. The present invention solves the above-mentioned problem by providing a lithium solid state battery including a cathode active material layer containing a cathode active material, an anode active material layer containing an anode active material, and a solid electrolyte layer formed between the above-mentioned cathode active material layer and the above-mentioned anode active material layer, wherein a reaction inhibition portion including a Li ion conductive oxide having a B—O—Si structure is formed at an interface between the above-mentioned cathode active material and a high resistive layer-forming solid electrolyte material that reacts with the above-mentioned cathode active material to form the high resistive layer.
