The composite of nitrogen-doped carbon (N-C) blend with lithium aluminum germanium phosphate (LAGP) was studied as cathode material in a solid-state lithium-oxygen cell. Composite electrodes exhibit high electrochemical activity toward oxygen reduction. Compared to the cell capacity of N-C blend cathode, N-C/LAGP composite cathode exhibits six times higher discharge cell capacity. A significant enhancement in cell capacity is attributed to higher electrocatalytic activity and fast lithium ion conduction ability of LAGP in the cathode.
研究了氮掺杂碳（N-C）与磷酸铝镓锂（LAGP）的复合材料作为固态锂-氧电池的阴极材料。复合材料电极对氧还原表现出高电化学活性。与 N-C 混合阴极的电池容量相比，N-C/LAGP 复合阴极的放电电池容量高出六倍。电池容量的显著提高归因于阴极中 LAGP 的更高电催化活性和快速锂离子传导能力。
