Abstract:
1. A manganese oxide material, wherein the material comprises a host material Q q Mn y O x , where Q is any element, q, y and x are each any number greater than zero, with a first dopant M and at least one further dopant substituted into the host material, the manganese oxide material having a layered structure in which ions are arranged in a series of generally planar layers stacked one on top of another with successive layers of oxide ions separated by alternating layers of Q ions and Mn ions, the layers thereby being arranged in a repeating sequence comprising a layer of Q ions, a layer of oxide ions, a layer of Mn ions and a further layer of oxide ions, with M ions and said at least one further dopant substituted into layers of Mn ions, producing a multiply doped material, wherein combinations of M and said at least one further dopant are selected from Ni, Co; Al, Co; Li, Co; Li, Ni; Li, Mg; Li, Cu; Li, Al and Li, Zn.
