Finally, although we primarily evaluated cycling performance at a single temperature (25°C), the relatively high ionic conductivity (~1-5 mS cm -1 ) of the LHCE gel from 0-80°C expands the scope of our findings to systems requiring lower and higher temperatures (e.g., electric vehicles in cold weather). Preliminary experiments at 60°C show promise for an alternative PVDF-HFP gel filled with an ionic liquid electrolyte (1.0 M LiFSI in PYR14TFSI).
