Abstract
The main object of the present invention is to provide an all solid state battery suitable for high rate charging. The present invention solves the problem by providing an all solid state battery including a battery element having a cathode active material layer, an anode active material layer, and a solid electrolyte layer formed between the cathode active material layer and the anode active material layer, characterized in that the anode active material layer contains graphite as an anode active material and a sulfide solid electrolyte, the graphite has a hardness of 0.36 GPa or more by a nanoindentation method, and the battery element is confined at a pressure more than 75 kgf/cm2.
