A manganese oxide material for use in electrochemical cells is provided, of the form Q q MN y M z O2, where Q is any Group I element, M is any element, Y is greater than zero and q and z are each greater than or equal to zero, and the material has a layer structure. Methods of preparing the manganese oxide material involve processing an intermediate material X x Mn y M z O2, where X is a Group I element not being lithium, M is any element, x and y are each greater than zero, and z is greater than or equal to zero, by an ion exchange reaction with a reactant containing lithium ions, to produce a material Li w Mn y M z O2, where w is greater than zero, and the material has a layered structure. Another method involves processing a precursor material and carrying out an ion removal reaction to remove Q and produce a material MN y M z O2. An electrochemical cell using the material of the present invention is also taught.
L'invention concerne un nouveau matériau stratifié s'utilisant dans des cellules électrochimiques, ainsi que son procédé de fabrication et une cellule le comportant comme électrode positive. Ce matériau se présente sous la forme QqMnyMzO2, où Q et M sont chacun un élément quelconque, y est un nombre quelconque supérieur à zéro, et q et z sont chacun un nombre quelconque supérieur où égal à zéro, et le matériau présente une structure stratifiée. L'invention concerne également des procédés de préparation de ce matériau à l'oxyde de manganèse, à l'aide d'une réaction d'échange d'ions ou d'une réaction d'extraction d'ions. L'emploi de ce matériau dans une cellule électrochimique est illustrée.
