1. An electrochemical generator comprising a cathode and an anode wherein at least one of which is a composite electrode comprising an active material, a current collector, and at least a first and a second solid electrolyte in the composite, at least one of the first and the second electrolyte comprising at least one dispersed electronic conduction additive;

  • the first electrolyte being a mineral solid conductor, the second electrolyte being solid and organic;

    wherein a layer of the first electrolyte coats at least part of the surface of the particles of the active material, to protect the coated surface of the particles from passivation or degradation reactions, and to maintain the quality of ionic and electronic exchanges between the active material of the composite electrode and other components of the composite electrode, the first electrolyte being impermeable to the second electrolyte.
