Abstract

Abstract

The unsustainability of traditional energy sources and environmental issues have led to an emphasis on new energy storage devices. Among them, supercapacitors have received widespread attention due to their high power density, long cycle life, and environmental friendliness. CR2032 coin cells were assembled using activated carbon as the cathode in both organic and aqueous electrolytes. At a scan rate of 0.1 mV/s, the specific capacitances of the organic and aqueous electrolytes were 143.44 and 156.58 F/g, respectively; at a current density of 0.1 A/g, the corresponding specific capacitances were 79.54 and 95.92 F/g. The organic system exhibited a maximum potential window of 1.8 V. After 600 cycles, the organic system demonstrated better stability in terms of specific capacitance and Coulomb cycle efficiency retention compared to the aqueous system. In contrast, the impedance behavior of the aqueous system was found to be superior.
