Synthesis And Electrochemical Properties Of Li1.3nb0.3cr0.4o2 As A High-Capacity Cathode Material For Rechargeable Lithium Batteries

A cation-disordered Li-excess cathode material on the binary system xLi(3)NbO(4)-(1 - x)LiCrO2 (x = 0.43) has been successfully prepared by mechanical milling, and delivers a high reversible capacity of approximate to 362 mA h g(-1), which originates from a highly reversible Cr3+/Cr6+ three-electron redox reaction with electrochemically inactive niobium ions.
