    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.

    摘要： The invention concerns an aprotic electrolytic composition located in the separator and in at least one composite electrode containing a powder of an active electrode material, and if necessary an electronic conduction additive of an electrochemical generator The electrolytic composition comprises a first polymer matrix consisting of a polyether and at least a second polymer matrix, macroscopically separated, and also at least an alkaline salt as well as a polar aprotic solvent: The polymer matrices are capable of being swollen by at least one of the polar aprotic solvents. The solvent or mixture of solvents is unevenly distributed between the polymer matrices. The invention also concerns an electrochemical generator comprising a negative electrode and positive electrode reversible to alkaline ions and a separator with polymer electrolyte, the electrolytic component of which is the composition described above. The invention further concerns the manufacture in two or three steps of a sub-assembly of an electrochemical generator by coating an electrode support with a composite electrode containing the second matrix, followed by a surface coating on the electrode resulting from the preceding step with a solution containing the first polymer matrix so as to form the separator wholly or partly.
