Abstract
An electrode for an all solid state battery includes at least a current collector, and an intermediate layer including a carbon structure that is disposed on the current collector. The carbon structure includes a spherical carbon material and a layered carbon material in amounts that allow for the formation of a lithium deposition separation space.
Claims20
An electrode for an all solid state battery, the electrode comprising:
- a current collector;
- and
- an intermediate layer comprising a carbon structure disposed on the current collector,
- wherein the carbon structure comprises:
- a spherical carbon material;
- and
- a layered carbon material;
- wherein the layered carbon material and the spherical carbon material are spaced in a configuration that forms a lithium deposition separation space.
An anodeless all solid state battery comprising:
- an anode current collector;
- an intermediate layer comprising a carbon structure disposed on the anode current collector;
- a solid electrolyte layer disposed on the intermediate layer;
- a cathode active material layer disposed on the solid electrolyte layer and including a cathode active material;
- and
- a cathode current collector disposed on the cathode active material layer,
- wherein the carbon structure comprises:
- a spherical carbon material and a layered carbon material wherein the spherical and layered carbon materials are spaced in a configuration that forms a lithium deposition separation space.
