FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, namely to two-layer electrochemical supercapacitor based on ionic liquids. According to the invention, in a two-layer supercapacitor containing electrodes of activated carbon, the electrolyte is made from a mixture of freon and ionic liquid, wherein freon is difluorochloromethane (freon-22), and the ionic liquid is tetrafluoroborate 1-butyl-3-methylimidazolium.
EFFECT: expansion of temperature range of operation of supercapacitor, which is in range from -140 °C to +150 °C, while maintaining performance of supercapacitor.
