▎ 摘　　要

NOVELTY - The device has an ionically conducting organic electrolyte that is provided with a mixture of a compressed gas solvent and the salts. The first component is selected from the group consisting of fluoromethane, difluoromethane, 1,1-difluoroethane, trifluoromethane, fluoroethane, trifluoroethane, tetrafluoroethane, pentafluoroethane, fluoroethylene, difluoroethylene, trifluoroethylene, tetrafluoroethylene, chloromethane, chloroethane, chloroethene, and isomers. The salts is selected from the group consisting of spiro-(1)-bipyrrolidinium tetrafluoroborate, dimethylpyrrolidinium tetrafluoroborate, ethylmethylpyrrolidinium tetrafluoroborate, diethylpyrrolidinium tetrafluoroborate, dipropylpyrrolidinium tetrafluoroborate, and dibutylpyrrolidinium tetrafluoroborate and isomers. The housing encloses the ionically organic electrolyte under a pressurized condition to maintain the compressed gas solvent. USE - Electrochemical capacitor device with organic electrolyte. ADVANTAGE - (1) The smaller size and molecular mass of the cation is provided over the common tetraethylammonium cation allow for higher conductivity in the electrolyte and higher cell capacitance. (2) The structure on the cation can greatly improve the solubility in difluoromethane and in other liquefied gas solvents. (3) The voltage and capacity of electrochemical capacitors is increased to maximize the energy stored in the device.
