    摘要： The present invention concerns a lithium electrochemical generator including at least one composite electrode comprising an active material and a first and second solid electrolytes non-homogeneously distributed into the composite. The first solid electrolyte is of mineral nature, vitreous or partly vitreous, and is a specific conductor of lithium ions, and is preferably localized on the surface of the particles of active materials of the electrode. The second solid electrolyte is organic, comprises a dry or gelified polymer electrolyte conducting ions surrounding the dispersed solid phases and acts as a deformable binder, preferably elastomeritically, of the composite in contact also with the collector and the separator electrolyte of the generator. A thin layer of the first electrolyte wets and coats at least a part of the surface of the active material particles to protect the coated surface of passivation or degradation reactions induced by the second electrolyte, and to maintain a good quality of ionic and electronic exchanges between the active material of the electrode and the other components of the composite, the first electrolyte being impermeable to the components of the second electrolyte.
