(EP890192-A1)      Aprotic electrolytic composition located in separator and in at least one composite electrode containing powder of active electrode material, and if necessary, an electronic conduction additive of electrochemical generator is claimed. Composition comprises first polymer matrix consisting of polyether, and at least a second polymer matrix, macroscopically separated, and also at least one alkaline salt, as well as a polar aprotic solvent.; said matrices being capable of being swollen by at least one of the aprotic solvents, solvent(s) being unevenly distributed between polymer matrices. Also claimed are electrochemical generator using said composition as electrolytic component, and method for manufacture of said generator.    USE -   As electrolytic component of electrochemical generator (claimed).    ADVANTAGE -   Level of swelling of matrices makes it possible to optimise locally the conducting properties of composite electrodes and mechanical properties of the separator.
