dc.description.abstractThis work present two-step synthesizes route to low-cost mesoporous carbon from coconut shell. The electrochemical characterization of the coconut shell based activated carbon (CSAC) material as electrode for supercapacitor showed a specific capacitance of 186 F g-1, energy density of 11 Wh kg-1 and power density of 325 W kg-1 at a 0.5 A g-1 with an excellent stability after floating for 100 h and cycling for 10000 cycles in polymer gel electrolyte. The CSAC showed very good potential as a stable material for supercapacitors desirable for high power applications.en_ZA
