ABSTRACT:
The invention provides a novel lithium manganese oxide compound in which oxygen anions, lithium cations and manganese cations are arranged in layers, each layer of lithium cations being sandwiched between two layers of oxygen anions, each layer of manganese cations being sandwiched between two layers of oxygen anions and each layer of oxygen anions being sandwiched between a layer of lithium cations and a layer of manganese cations. The invention also provides a method of making the compound; and an electrochemical cell employing the compound as its cathode.
