Tape-cast Ce-substituted Li7La3Zr2O12 electrolyte for improving electrochemical performance of solid-state lithium batteries

Li 7 La 3 Zr 2− x Ce x O 12 ( x = 0–0.15) garnet and a tape casting process are developed to increase electrolyte Li + conductivity and reduce the interface resistance, which significantly improve the performance of solid-state lithium-metal batteries.
