Mesoporous Nitrogen-Doped Carbon-LiSICON Glass Ceramics as High Performance Cathodes in Solid-State Lithium Oxygen Batteries.

摘要

Here we report the use of N-C blend with 20 wt% LAGP (composite 3) in the cathode of a solid-state lithium-oxygen cell with superior discharge cell capacity compared to the cell performance with composite 1 and composite 2. The improvement in cell performance is due to the superior electrochemical activity of composite 3 for the reduction of oxygen and the higher ionic conductivity of LAGP to transport lithium ions in the composite matrix.
