Abstract
The present invention is directed to a higher power, thin film lithium-ion electrolyte on a metallic substrate, enabling mass-produced solid-state lithium batteries. High-temperature thermodynamic equilibrium processing enables co-firing of oxides and base metals, providing a means to integrate the crystalline, lithium-stable, fast lithium-ion conductor lanthanum lithium tantalate (La1/3-xLi3xTaO3) directly with a thin metal foil current collector appropriate for a lithium-free solid-state battery.
Claims5
A solid-state lithium battery comprising:
- a metallic anode current collector layer,
- a perovskite lanthanum lithium tantalate electrolyte layer on the metallic anode current collector layer,
- a cathode layer on the electrolyte layer, and
- a cathode current collector layer on the cathode layer.
