Abstract: A lithium rich partially cation disordered transition metal oxide cathode material is provided that exhibits reduced voltage hysteresis, reduced or inhibited transition metal migration and increased capacity and energy storage compared with layered oxides. The lithium rich cathode material is based on Li1+xCr1?x-yMyO2 where M is a transition metal with limited redox activity, such as Mn4+, Ti4+, Zr4+, Sn4+, Nb5+, Ta5+, and W6+, and where 0<x<0.33 and 0<y<0.67. Cation disordering is induced in the material that alters both the structure and the electrochemistry and effectively mitigate voltage hysteresis and increase the reversibility of the Cr3+/Cr6+ redox couple and the energy capacity. Lithium transport in the cation-disordered structure occurs through a percolation network of Li-rich tetrahedral environments.
