Abstract:
An electrolytic component for an electrochemical generator comprising a first polymer matrix and a second polymer matrix,wherein said first polymer matrix comprises a polyether, at least one first polar aprotic solvent and at least one alkali metal salt, said first polar aprotic solvent causing said polyether to swell to provide a first gel,said second polymer matrix comprises a second polymer, at least one second polar aprotic solvent and at least one alkali metal salt, said second polar aprotic solvent causing said second polymer to swell to provide a second gel,said first and second polymer matrices are disposed in contact with each other,said first and second polar aprotic solvents are unequally distributed between said first and second polymer matrices, thereby providing a macroscopic separation between said first and said second matrices.
