Methods of making interpenetrating polymeric networks, anode and cathode half elements and their use in forming electrochemical cells

摘要

An interpenetrating polymeric network containing a liquid electrolyte for use in solid state electrochemical cells is formed by mixing a liquid monomeric or prepolymeric radiation polymerizable compound, a radiation inert ionically conducting liquid, and an ionizable alkaline metal salt, and subjecting the mixture to actinic radiation to thereby crosslink the radiation polymerizable ionically conducting material and form a solid matrix containing the ionically conducting liquid. Electrode half elements and electrochemical cells incorporating the polymeric network are also described.
