Self-protection of electrochemical storage devices via a thermal reversible sol-gel transition

Abstract

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