Abstract
In order to expand the range of electrolytes for low-temperature double-layer supercapacitors, the possibility of using a 2.5 M solution of PCIs in anhydrous hydrogen fluoride as an electrolyte using electrodes made of activated carbon cloth CH-900-20 was investigated. It has been established that when the temperature decreases from +20 to −65°C, the specific capacity of activated carbon cloth in such an electrolyte decreases linearly from 225 to 200 F/g. Replacing PCl with PO results in the appearance of water in the electrolyte due to neutralization and the appearance of a noticeable pseudo-capacitance at positive temperatures and a decrease in capacity at a temperature of −65°C.
