An ionically conducting solid polymer electrolyte is a complex of a homopolymerised or copolymerised N,N-disubstituted acrylamide with an alkali metal salt say lithium perchlorate. The acrylamide polymer units have the formula <IMAGE> R<1> and R<2> may vary widely, and are e.g. methyl, or R<1>-N-R<2> may form a ring. The complex is formed by dissolution of the acrylamide polymer and salt in a solvent followed by evaporation of the solvent, or by polymerisation of the acrylamide monomer in the presence of the salt and optionally a co-solvent, e.g. N,N-dimethylacetamide, which can act as plasticizer. |
