Abstract
A main object of the present disclosure is to provide a method for producing an all solid state battery capable of satisfying both of improving capacity durability and suppressing the increase of an initial resistance. The above object is achieved by providing a method for producing an all solid state battery, the method comprising: a preparing step of preparing an all solid state battery including a cathode layer, a solid electrolyte layer, and an anode layer, in this order; and an initial charging step of initially charging the all solid state battery, wherein the anode layer includes a metal particle capable of being alloyed with Li, and having two kinds or more of crystal orientation in one particle, as an anode active material, and in the initial charging step, the all solid state battery is charged to a battery voltage of 4.35 V or more and 4.55 V or less.
