Abstract
The composition and method for depositing and processing a solid transparent electrolyte polymerized by ultraviolet (UV) radiation are described. The electrolyte composition includes, at least, an ionic compound, a polymerizable material, a photoinitiator and a polar solvent. The electrolyte is deposited by printing techniques, such as inkjet printing.
