Material consisting of composite oxide particles, method for preparing same, and use thereof as electrode active material
Abstract:
A positive electrode material, having particles having a complex oxide OC1 core, an at least partial complex oxide OC2 coating, and an adhesive carbon surface deposit. The material is characterized in that the complex oxide OC1 is an oxide having a high energy density and in that the oxide OC2 is an oxide of a metal having a catalytic effect on the reaction of the carbon deposit, the oxide having good electronic conductivity. The presence of the OC2 layer facilitates the deposit of a carbon adhesive layer at the surface of the oxide particles, and improves the conductivity of the material when the latter is used as an electrode material. The electrode material can particularly be used in the manufacture of a lithium battery.
