Hybrid supercapacitors: A simple electrochemical approach to determine optimum potential window and charge balance

In this work, we introduced novel, and simple electrochemical principles to guide the choice of the safe and valid operating potential window profile for carbon-based hybrid supercapacitor. The start vertex potential of the cyclic voltammograms (CVs) is set as the potential of zero charge (PZC). However, the final potential limit is chosen after elucidation of the storage mechanism using the CVs measured at various potential scan rates across...
