Abstract:
A manganese oxide material wherein the material is of the form Q.sub.q Mn.sub.y M.sub.z O.sub.2, where Q is a group I element, M is another element, .sub.y is a number greater than zero, .sub.q and .sub.z are each a number greater than or equal to zero, wherein the material comprises a layered structure of ions, 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, 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.
