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 (LiO) and a cobalt oxide phase. For example, the composite cathode active material can be layered LCO in a solid solution matrix of one of LiO—LiCoO—CoO, LiO—LiCoO and LiO—CoO, 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.
