Abstract : PMMA-based gel electrolytes have the prerequisites for their exploitation as electrolytic membranes in practical electrochemical devices. In particular the high ionic conductivities, the elevated electrochemical stability windows and the satisfactory Li(+) transference numbers confer to these membranes the suitability for their use in the realization of lithium based high energy density rechargeable batteries. Moreover, the PMMA-based gel electrolytes have shown a complete retention of the gelating solvents as the result of a good interaction between the polymeric chains and the solvent molecules. Therefore the surfaces of the films are not wetted and a lower reactivity with the lithium anode (of the batteries) is expected.
