英文摘要Gel electrolytes are of great importance for supercapacitors (SCs) operating at high temperatures. However, it is a fundamental challenge for SCs using aqueous gel electrolytes at elevated temperatures to ensure good work durability due to the evaporation of water. Here we report a "water-in-salt" gel electrolyte that exhibits superior water-retention and even water-absorption capability. What is noteworthy is that a quasi-solid-state SC utilizing the gel electrolyte is able to work and exhibit long cycling life across a wide temperature range from room temperature up to 120 degrees C in an extremely dry atmosphere, representing the best record among the previously reported aqueous gel-based SCs, as far as we know. This strategy may provide a new way to develop reliable aqueous gel electrolytes for SCs operating at high temperatures.
