Method for preparing ultralow-temperature high-capacity supercapacitor and use thereof |
| abstract |
The present invention provides a method for preparing an ultralow—temperature high—capacity supercapacitor. The electrode material used is a composite porous carbon material having micropores and mesopores, and having a specific surface area greater than 2500 mZ/g, Where the pore size of the micropore is larger than 0.8 nm, the pore size of the mesopore is from 2 to 3.0 nm, and the micropores account for above 70%. The electrolytic solution for the supercapacitor is a mixed solvent of l, 3—dioxolane (or methyl formate MF, or a mixture of the two) and acetonitrile, and spiro quaternary ammonium tetrafluoroborate SBP—BF4 is dissolved. The supercapacitor prepared based on the electrode material in combination With the electrolytic solution has a mass specific capacitance greater than 150 F/g and a volume specific capacitance greater than 80 F/cm3 at —lOO°C and a current density larger than 1 A/g. |
