Method of preparing polymeric electrolytes

摘要

A method of fabricating polymeric matrices suitable for use in non-aqueous electrochemical cells is provided. The method includes forming an organic emulsion comprising an organic solvent and having a polar phase comprising polar polymer precursors and a non-polar phase comprising non-polar polymer precursors wherein the polar phase is substantially immiscible in the non-polar phase, said emulsion further including an effective amount of surfactant to maintain said emulsion; and initiating polymerization of said polar polymer precursors to form first polymers and of said non-polar polymer precursors to form second polymers wherein said first polymers are crosslinked by said second polymers to form a polymeric matrix. The polymeric matrix will have superior physical strength and puncture resistance.
