Abstract
A separator for a battery formed from a polymer gel electrolyte that is disposed within the pores of a polymer mesh. The polymer gel electrolyte is formed from a crosslinked ion-conducting polymer and an ionic liquid. The separator is formed from a gel loaded with an electrolyte, which prevents issue with electrolyte leakage. The polymer mesh provides stability to the polymer gel electrolyte, allowing for use of thin films of the polymer gel electrolyte and use of soft polymer gel electrolytes.
