摘要： 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.

摘要： Particles comprising a core and a coat covering at least part of the core surface. The core has more than 50% of an acidic metal oxide and the core coating is based on a polymer, preferably based on a soiled polymer with high electrochemical stability. The particle has a solubility rate (ts), in fixed time, of the metal oxide migrating towards the electrolyte, per cycle, which is less than 5 per 10000. The particles are obtained by mixing the polymer and a metal oxide, via dry process with addition of solvent. The electrodes constituting an electrode substrate at least partly coated with a mixture consisting of at least 40 of those particles have remarkable electrochemical properties, in particular regarding the lifetime of batteries in which they are incorporated.
