1. Introduction Low-cost, safe and durable energy storage systems are required for smart grids and other stationary applications [1, 2]. To that end, aqueous batteries and supercapacitors have garnered tremendous research interest due to high safety .
High capital cost and low energy density of supercapacitors make the unit cost of energy stored (kWh) more expensive than alternatives such as batteries. Their attributes make them attractive for uses in which frequent small charges/discharges are required (e.g., ensuring power quality or providing frequency regulation).
Developing highly reliable electrochemical energy storage (EES) devices over a wide-temperature range are urgent for some extreme application. Conventional electrolytes commonly make EES operate at only −30–60 °C since they suffer from sluggish ion-transport kinetics at low temperature while decomposition failure at high temperature.
