It is an object of this invention to provide new solid electrolytes. Another object of this invention is to provide new polymeric electrolytes. A further object of this invention is to provide polymeric electrolytes that have high conductivities at room temperature and that have good mechanical strength. These and other objects of this invention are accomplished by providing: a solid polymeric electrolyte comprising a two-phase interpenetrating polymer network of 1) a mechanically supporting phase of a continuous network of a crosslinked polymer selected from the group consisting of epoxies, polyurethanes, polymethacrylates, polyacrylates, polyacrylonitriles, and polystyrenes; and 2) an ionic conducting phase comprising a) a metal salt complexing liquid polymer selected from the group consisting of poly(ethylene oxide), poly(propylene oxide), poly(ethylene imine), and mixtures, complexed with b) a metal salt selected from the group consisting of LiI, LiBr, LiClO/sub 4/, CsClO/sub 4/, NaI, NaBr, CsI, CsBr, KI, KBr, LiCF/sub 3/SO/sub 3/, LiSCN, CsSCN, NaSCN, KSCN, AgNO/sub 3/, CuCl/sub 2/, CoCl/sub 2/, Mg(ClO/sub 4/)/sub 2/, PbBr/sub 2/, MgCl/sub 2/, and mixtures thereof wherein from more than zero to 0.50 moles of metal salt are added per mole of monomer repeat unit of the metal salt complexing liquid polymer. The mechanically supporting phase comprises from 20 to 55 wt. % of the solid polymeric electrolyte with the ion conducting phase being essentially the remainder.
