Abstract
Individual electrodes for a solid-state lithium-ion battery cell may be formed, for example, by elevated temperature consolidation in air of a mixture of resin-bonded, electrode active material particles, oxide solid electrolyte particles, and particles of a non-carbon electronic conductive additive. Depending on the selected compositions of the electrode materials and the solid electrolyte, one or both of the cathode and anode layer members may be formed to include the non-carbon electronic conductive additive. The battery cell is assembled with the solid-state electrodes placed on opposite sides of a consolidated layer of oxide electrolyte particles. The electronic conductivity of at least one of the cathode and anode is increased by the incorporation of particles of a selected non-carbon electronic conducive additive with the respective electrode particles.
