Abstract:
1. A solid state battery including at least one multilayered battery cell comprising: 1) a solid state layer of negative electrode material capable of adsorbing and desorbing protons during charge and discharge; 2) a solid state layer of positive electrode material capable of desorbing and adsorbing protons during charge and discharge; and 3) a solid state layer of perovskite-type oxide material disposed between said layer of positive electrode material and said layer of negative electrode material, where said layer of perovskite-type oxide material consists of perovskite-type oxide and is electrically insulating and capable of readily conducting or transporting protons from said layer of positive electrode material to said layer of negative electrode material while said battery is charging and from said layer of negative electrode material to said layer of positive electrode material while said battery is discharging; said perovskite material having a room temperature hydrogen conductance in the range of 0.0231 to 91 S/cm.
