Hierarchical porous carbon derived from petroleum coke <i>via</i> one-step chemical activation for the fabrication of a supercapacitor and real time clock application

Abstract

in aqueous and organic electrolytes, respectively. Further, a coin cell supercapacitor was fabricated using the pet-coke derived porous carbon in an organic electrolyte with a potential window of 2.7 V, demonstrating superior rate capability and durability. The calculated energy and power density of the fabricated coin cell indicate its favorable supercapacitor application to act as a backup power source for real time clock (RTC) application in electronics.
