Classification: CPC H  C  Y | IPC H

Claim 11:
12. An electrochemical device comprising:
a cathode comprising a lithium host material phase;
an anode comprising lithium metal, or a lithium host material phase;
a solid-state electrolyte configured to facilitate the transfer of ions between the anode and the cathode; and
a solid-state conductive material phase comprising a ceramic material having a crystal structure and a dopant in the crystal structure, the conductive material having a lithium-ion conductivity and an electronic conductivity wherein the electronic conductivity of the conductive material is greater than a reference electronic conductivity of a reference material comprising the ceramic material having the crystal structure without the dopant in the crystal structure, the conductive material filling at least part of at least one of a first structure of the lithium host material of the cathode or a second structure of the lithium host material of the anode,
wherein the dopant is selected from the group consisting of transition metal ions and mixtures thereof, and
wherein the cathode or the anode does not include a separate phase, other than the lithium host material phase and the solid-state conductive material phase, that provides an electrical pathway from a current collector to the lithium host material phase.
