PROBLEM TO BE SOLVED: To provide a positive electrode material having a high energy density and a good electronic and ionic conductivity.SOLUTION: A positive electrode material comprises particles having a core of a complex oxide CO1, an at least partial coating of a complex oxide CO2 and an adherent surface deposit of carbon. In the material, the complex oxide CO1 has a potential of greater than 2.5 V and is selected from oxides of an alkali metal and of at least one element selected from among Mn, Co, Ge, Au, Ag and Cu, and the oxide CO2 is an oxide of an alkali metal and of at least one metal which has a catalytic effect on the reaction for the deposition of carbon and is selected from among Fe, Mo, Ni, Pt and Pd. |
