The electrolyte, responsible for ion transport, is the key factor determining the supercapacitors'' low-temperature capabilities. However, conventional electrolytes, with their high freezing points and slow ion transport kinetics, limit the applications of supercapacitors in low-temperature environments.
The supercapacitor still has a promising capacitive performance (75.5 F g −1 at −20 °C and 306.5 F g −1 at 60 °C) and excellent cycling stability (over 15000 cycles) at the low or high temperature when charged at 1.2 A g −1 under 1.5 V.
Finally, we have provided an outlook on the current challenges and future development directions of low-temperature electrolytes, which is expected to offer promising strategies for reliable, high-performance supercapacitors in ultra-low temperature applications.
To enable supercapacitors to operate under colder conditions, several approaches have been introduced to decrease the freezing point and enhance ionic conductivity, with the most effective approaches including introducing anti-freezing additives, increasing electrolyte concentration, and utilizing deep eutectic solvents (DESs).
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
