Abstract
The present invention is directed to both an electrolyte solution for use as a gel electrolyte in an electrolytic cell, and a process for making both the electrolyte gel and the electrolytic cell. The electrolyte solution comprises a polymerizable electrolyte material and a reinforcement polymer. The reinforcement polymer preferably consists of at least poly(methyl methacrylate), while the polymerizable electrolyte material comprises at least a solvent, a monomer, a polymerization initiator, and an ionic conductor. The use of a reinforcement polymer increases the homogeneity and thus the coatability of the electrolytic solution, while also improving the mechanical properties of the cured electrolyte gel.
