Abstract From the Canadian patent

A method for forming an interpenetrating polymeric network containing a liquid electrolyte for use in solid state electrochemical cells which comprises forming a mixture of a liquid monomeric or prepolymeric radiation polymerizable, compound, a radiation inert ionically conducting liquid, and an ionizable alkaline metal salt; subjecting said mixture to actinic radiation to thereby crosslink said radiation polymerizable ionically conducting material and form a solid matrix containing said ionically conducting liquid; and electrode half elements and electrochemical cells incorporating said network.
