Electrochemical properties and structures of the mixed-valence lithium cuprates Li sub(3)Cu sub(2)O sub(4) and Li sub(2)NaCu sub(2)O sub(4)

The electrochemical performances of Li sub(3)Cu sub(2)O sub(4) and Li sub(2)NaCu sub(2 )O sub(4) as cathode materials in lithium coin type batteries have been studied. In Li sub(3)Cu sub(2)O sub(4), the copper was oxidised to the III level when cycling. The replacement of the lithium by the sodium i...

Zusammenfassung:The electrochemical performances of Li sub(3)Cu sub(2)O sub(4) and Li sub(2)NaCu sub(2 )O sub(4) as cathode materials in lithium coin type batteries have been studied. In Li sub(3)Cu sub(2)O sub(4), the copper was oxidised to the III level when cycling. The replacement of the lithium by the sodium ions in the octahedral sites in Li sub(2)NaCu sub(2)O sub(4) might have an effect on the pathway of the lithium ions during the (de)intercalations. copyright 2001 Elsevier Science B.V.
