Patent ID: 7135252

Claim:
A lithium metal oxide positive electrode for a non-aqueous lithium cell prepared in its initial discharged state having a general formula xLiMO 2 .(1-x)Li 2 M′O 3 in which 0<x<1, and where M is more than one ion selected from V, Mn, Fe, Co, and Ni with an average oxidation state of three with at both Ni and Mn being present in a Mn:Ni ratio of 1:1 and where M′ is one or more ions selected from Mn, Ti, Zr, Ru, Re, and Pt with an average oxidation state of four, wherein both the LiMO 2 and Li 2 M′O 3 components are layered and the ratio of Li to M and M′ is greater than one and less than two.
