Thin-film, solid state battery employing an electrically insulating, ion conducting electrolyte material

A solid state battery comprising:

• A.) a substrate;
• B.) at least one multilayered electrochemical cell deposited onto said substrate, said multilayered electrochemical cell comprising:
• 1. ) a solid state layer of negative electrode material capable of electrochemically adsorbing and desorbing both protons and lithium ions during charge and discharge;
• 2.) a solid state layer of positive electrode material capable of electrochemically desorbing and adsorbing both protons and lithium ions during charge and discharge;
• and
• 3.) a solid state layer of insulating/conducting material disposed between said layer of positive electrode material and said layer of negative electrode material, where said layer of insulating/conducting material is electrically insulating and capable of readily conducting or transporting both protons and lithium ions 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;
• and
• C.) an electrically conductive layer deposited a top the last of said at least one multilayered electrochemical cells, said electrically conductive layer providing one battery terminal.
