Thermal self-protected intelligent electrochemical storage devices are fabricated using a reversible sol-gel transition of the electrolyte, which can decrease specific capacitance and increase enable temperature-dependent charging discharging rates in device. This work represents proof simple useful concept, shows tremendous promise for safe controlled power delivery devices.
