Abstract
An electrode material comprising a composite lithium metal oxide, which in an initial state has the formula: y[xLiMO.(1−x)LiM'O].(1−y)LiMnM″O; wherein 0≤x≤1; 0.75≤y<1; 0<z≤2; 0≤d≤0.2; and z−d≤2. M comprises one or more metal ions that together have an average oxidation state of +4; M′ comprises one or more metal ions that together have an average oxidation state of +3; and M″ comprises one or more metal ions that together with the Mn and any excess proportion of lithium, 'd', have a combined average oxidation state between +3.5 and +4. The LiMnM″Ocomponent comprises a spinel structure, each of the LiMOand the LiM′Ocomponents comprise layered structures, and at least one of M, M′, and M″ comprises Co. Cells and batteries comprising the electrode material also are described.
