1. A sulfide solid battery system comprising:

  • a solid battery including a cathode layer, an anode layer and a solid electrolyte layer disposed between the cathode layer and the anode layer; and

    a controller capable of controlling a charge-stopping voltage of the solid battery,whereinLiNixCoyMnzO2 (x+y+z=1 and 0.32<

    x, y, z<

    0.34) is employed for the cathode layer and a sulfide solid electrolyte is employed at least for the solid electrolyte layer, andthe charge-stopping voltage of the solid battery is controlled by the controller in charging the solid battery so that the charging is stopped at 4.3 V or less with reference to a potential at which graphite stores/releases lithium ions.
