Lithium Intercalation Cells Without Metallic Lithium and

摘要: The authors studied the possibility of using a reducing intercalation compound such as MoO/sub 2/ or WO/sub replacement for metallic lithium in secondary electrochemical cells. In order to be practical importance, cell this type requires good reversibility at both electrodes and substantial potential difference between two electrodes. Coupled with highly oxidizing positive electrode LiCoO/sub 2/, they find that are feasible substitutes negative With improvements cycling efficiency, materials these could improve overall performance
