Abstract
A method of producing a solid electrolyte for an electrochemical cell, the cell comprising at least one first complexing polymer presenting in its monomer pattern at least one heteroatom and at least one ionizable alkaline salt complexed in the said polymer, wherein said complexing polymer is mixed with at least one second polymer miscible with the said complexing polymer and having cross-linkable functions; said cross-linkable functions then being physically cross-linked, with the complexing polymer being brought to an essentially amorphous state during said cross-linking operation. The electrolyte obtained can be used in electrochemical cells operating at ambient temperature.
