The present invention relates to a positive electrode material consisting of particles having a core of composite oxide CO1, at least a partial coating of composite oxide CO2, and an adherent carbon surface deposit. The material is a composite oxide CO1 is an oxide having a high energy density, and the oxide CO2 is a metal oxide having a catalytic effect on the carbon adhesion reaction, and the oxide has good electron conduction. It has the property. The presence of the CO2 layer facilitates the adhesion of the carbon adhesion layer on the surface of the oxide particles and improves the conductivity of the material when it is used as an electrode material. The electrode material can be used in particular for the production of lithium batteries. [Selection] Figure 1 |
