Abstract: A cathode for a solid-state battery comprises a composite cathode active material formed of a layered lithium cobalt oxide (LCO) in a solid solution matrix of lithium oxide (Li2O) and a cobalt oxide phase. For example, the composite cathode active material can be layered LCO in a solid solution matrix of one of Li2O—LixCo1-xO—Co3O4, Li2O—LixCo1-xO and Li2O—Co3O4, with 0?x?0.5. The LCO is at least 80 wt. % of the composite cathode active material. The cathode is a sintered solid-state cathode wafer that is free-standing, upon which solid-state battery cells are fabricated.

Abstract: Rechargeable, high-density electrochemical devices are disclosed. These electrochemical devices may, for example, include high energy densities that store more energy in a given, limited volume than other batteries and still show acceptable power or current rate capability without any liquid or gel-type battery components. Certain embodiments may involve, for example, low volume or mass of all of the battery components other than the cathode, while simultaneously achieving high electrochemically active mass inside the positive cathode.
