Abstract
A solid state Li battery and an all ceramic Li-ion battery are disclosed. The all ceramic battery has a solid state battery cathode comprised of a mixture of an active cathode material, an electronically conductive material, and a solid ionically conductive material. The cathode mixture is sintered. The battery also has a solid state battery anode comprised of a mixture of an active anode material, an electronically conductive material, and a solid ionically conductive material. The anode mixture is sintered. The battery also has a solid state separator positioned between said solid state battery cathode and said solid state battery anode. In the solid state Li battery the all ceramic anode is replaced with an evaporated thin film Li metal anode.
