High Surface Area Activated Carbon from Rice Husk as a High Performance Supercapacitor Electrode

In this study, we report on the application of high surface area activated carbon (AC) derived from rice husks as a supercapacitor electrode. The prepared AC was free from Brønsted or Lewis acid sites, thus making the electrical double layer capacitance as the main charge storage mechanism. Three sa...
