Abstract
Supercapacitors with a commercial-level mass loading of active materials are designed to offer greater energy storage capacity than conventional supercapacitors. For the first time, we are reporting the fabrication and performance studies of a symmetric supercapacitor with 30 mg cm−2 commercial-level mass loading of 2D WS2 nanoflower electrode material, which exhibited superior electrochemical performance. At 5 mV s–1 specific capacitance achieved by the device is 204 F g–1. At 1 A g–1, the supercapacitor provides impressive specific energy and power values of 14 Wh kg−1 and 0.8 kW kg−1, respectively. The device maintains an exceptional cycling stability of 100 % over 10,000 cycles of continuous charging and discharging. Furthermore, supercapacitor coin cells fabricated using commercial-level-mass loaded 2D WS2 electrodes are used to power an LED.
