Mesoporous Nitrogen Doped Carbon-Glass Ceramic Cathode for High Performance Lithium-Oxygen Battery.

摘要

The composite cathode prepared from highly mesoporous nitrogen doped carbon (N-C) blend and lithium aluminum germanium phosphate (LAGP)-glass ceramic has been explored for its application in an all solid-state lithium-oxygen cell. The composite cathode exhibits remarkable enhancement in cell capacity in comparison to N-C blend cathode. This enhancement is ascribed to the mesoporous structure and higher electrocatalytic activity of cathode materials as well as fast lithium ion conduction of LAGP in the cathode.
