- Аннотация: In order to expand the range of electrolytes for low-temperature double-layer supercapacitors, the possibility of using a 2.5 M PCl5 solution in anhydrous hydrogen fluoride as an electrolyte combined with electrodes made of activated carbon cloth CH-900-20 was investigated. Upon the temperature decrease from +20 to –65°C, the specific capacity of the activated carbon cloth in this electrolyte was shown to decrease linearly from 225 to 200 F/g. The replacing of PCl5 with P2O5 resulted in the appearance of water in the electrolyte, due to the latter’s interaction with HF, the appearance of a noticeable pseudocapacitance at positive temperatures, and a decrease in the capacity at the temperature of ‒65°C.
