Abstract
A solid state battery comprising a substrate; at least one multilayered electrochemical cell deposited onto the substrate, each multilayered electrochemical cell comprising: a layer of disordered hydrogenated carbon material negative electrode material capable of electrochemically adsorbing and desorbing lithium ions or both lithium and hydrogen ions during charge and discharge; a layer of positive electrode material capable of electrochemically desorbing and adsorbing lithium ions or both lithium and hydrogen ions during charge and discharge; and a layer of insulating/conducting material disposed between the layer of positive electrode material and the layer of negative electrode material, where the layer of insulating/conducting material is electrically insulating and capable of readily conducting or transporting lithium ions or both lithium and hydrogen ions from the layer positive electrode material to the layer of negative electrode material while the battery is charging and from the layer of negative electrode material to the layer of positive electrode material while the battery is discharging; and an electrically conductive layer deposited a top the last of the at least one…
