Abstract

An electrode for a lithium-ion cell comprising a 'layered-spinel' composite oxide material is disclosed. The 'layered-spinel' can be a material of formula xLiMO.(1−x)LiM'O, wherein 0<x<1; LiMOis a lithium metal oxide having a layered structure in which M comprises one or more transition metals and optionally lithium, and has a combined average oxidation state of +3; and LiM′Ois a lithium metal oxide having a spinel structure, 1≤y≤1.33, 1.66≤z≤2, and M′ comprises one or more transition metals, and has a combined average metal oxidation state in the range of about +3.5 to about +4.
