The high temperature performance of water-in-salt electrolytes was investigated using a carbon-based electrode with commercial cell components. Supercapacitors using 21 m Li bis(trifluoromethylsulphonyl)imide (TFSI) and 21 m LiTFSI + 7 m Li trifluoromethanesulphonyl electrolytes are shown to operate at a voltage of 2 V at 100 °C and 120 °C, respectively, with gravimetric capacitances exceeding 100 F g-1.
使用具有商业电池组件的碳基电极研究了盐包水电解质的高温性能。结果表明，使用21 m Li双（三氟甲基磺酰）亚胺（TFSI）和21 m LiTFSI + 7 m 三氟甲磺酸锂电解质的超级电容器分别在100°C和120°C下以2 V的电压运行，其重量电容超过100 F g-1。
