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.

Keywords: electrochemical storage devices; self-protection; sol-gel transition; thermal runaway.
