Abstract (en)

[origin: WO9841476A1] A lithiated metal oxide of the general formula: LiayMbxM'b(1-x)Obz, where a is 1 or 2, b is 1 or 2, 0</=x</=1, 0<y</=1, 1.8</=z</=2.2 and M and M' are multi-valent metals, a method of synthesizing such lithiated metal oxides, and a rechargeable lithium-based battery having at least one electrode in which such a lithiated metal oxide is used as an active material. The process comprises combining at least one lithium carboxylate or lithium alkoxide salt, at least one metal carboxylate salt and an alcohol solvent; reacting the combination in the presence of heat; drying the reaction mixture to remove volatile byproducts and solvent; and heat treating.
