Transcribed Image Text:

(a) A symmetric supercapacitor cell consisting of reduced graphene oxide(r-GO) as electrode material having a mass of 0.5 mg for each electrode. Cyclic Voltammetry (CV) was taken at a scan rate of 50 mV/s. The original data obtained from CV is given in the excel sheet as attached. Calculate the specific capacitance (in F/g). (b) By using the same supercapacitor cell, galvanostatic charge discharge curves were also measured at a constant current of 0.1 A. The original data obtained from GCD is given in the excel sheet as attached. Calculate the specific capacitance (in F/g).
