Wide temperature range- and damage-tolerant microsupercapacitors from salt-tolerant, anti-freezing and self-healing organohydrogel via dynamic bonds modulation

An organohydrogel electrolyte featured with high salt tolerance, ultralow freezing point, and strong self-healing ability is experimentally realized via modulating dynamic bonds. The organohydrogel-based MSCs exhibit a boosted energy density and promising wide temperature range- and damage-tolerance, shedding light on the development of flexible micropower devices.
