| Abstract | ||||
| This study investigates the electrochemical evaluation of the activated carbon (AC) prepared from pomegranate peels which were collected, dried, carbonized and finally activated with KOH at different temperatures. The characterization of the as-prepared AC revealed an amorphous type of carbon and densely layer-stacking sheets with an interconnected micro porous network with a remarkable 3128.86m2g-1 surface area. The as-synthesized AC displayed a remarkable capacitance of 126 F g-1 at 0.5 A g-1with a storage retention of 137 % after 2000 cycles at a current density of 2 A g-1. Meanwhile, the realistic symmetrical simulation has been installed, it shows an energy density of 4.58 W h kg-1 at a power density of 244 W kg-1 with a storage retention of 66 % of the initial capacity at a current density of 2 A g-1 after 2000 cycles. Overall, these results demonstrate that for supercapacitors evaluation, the AC electrode can be considered a successful electrode material. | ||||
