Is the capacitive contribution to the total capacitance obtained from CV need lie inside the area of CV plot?

Dear friends, it is well known that the total capacitance = surface capacitance + intercalation capacitance (i(V)/v^1/2 = k1 v^1/2+K2) for the composite electrode materials, and the concept...

Is it possible to calculate power density from CV curves of a supercapacitors?

Dear friends. it is well known calculating power density (p) charge/discharge curves using formulae of P=E/td and P= V^2/ESR, and both of the formulae use GCD curves for the calculation. Now is it...

Why 1M H2SO4 can not be used as electrolyte for supercapacitors involving Ni(OH)2? Why potential window more than 0.7 V can not be used for Ni(OH)2 ?

it is generally said that the full potential window of aqueous electrolytes (1.2 V) can not be used for supercapacitors containing electrodes made up of Ni(OH)2 , but what is the harm in it, if...

How the potential window of aqueous electrolytes can be extended beyond 1.23V in asymmetric supercapacitor cells without electrolysis of electrolyte?

Potential window offered by aqueous electrolytes is 1.23 V, which is due to the fact that beyond 1.23 V the aqueous electrolytes will undergo electrolysis (common in symmetric supercapacitors)....
