Abstract
Provided is a bipolar all-solid-state sodium ion secondary battery that can increase the voltage without impairing safety. A bipolar all-solid-state sodium ion secondary battery includes: a plurality of all-solid-state sodium ion secondary batteriesin each of which a positive electrode layercapable of absorbing and releasing sodium, a solid electrolyte layermade of a sodium ion-conductive oxide, and a negative electrode layercapable of absorbing and releasing sodium are laid one upon another in this order; and a current collector layerprovided between the positive electrode layerof each of the plurality of all-solid-state sodium ion secondary batteriesand the negative electrode layerof the adjacent all-solid-state sodium ion secondary batteryand shared by the positive electrode layerand the negative electrode layer
