Even if the charge discharge is for a short period (> a few minutes), such materials will store a higher charge. Peak separations in pseudocapacitive materials can be caused by an ohmic loss at high rates . From the CV and GCD analysis, the pseudocapacitive and battery-like behavior are more evident and obvious.
Through a series of characterization procedures, the electrochemical process should be linked to a charge transfer mechanism. The electrochemical behavior of pseudocapacitive materials should also be probed at time scales of less than 10 min, as this is when they demonstrate better capacity and efficiencies than ordinary battery materials .
