Boosting the Capacitance of an Aqueous Zinc-Ion HybridEnergy Storage Device by Using Poly(3,3′-dihydroxybenzidine)-ModifiedNanoporous Carbon Cathode

Abstract

Aqueous electrochemical energy storage devices are highly safe, low cost, and environmentally benign, yet suffer from low energy storage capacity. Here, we devise a novel cathode material for makin...
