Supercapacitors are of high importance as electrochemical energy storage devices attributing to their outstanding power performance, excellent reversibility and long cycle life. But meanwhile, they suffer from low energy when compared with batteries. Pseudocapacitive materials with a high theoretical capacitance hold a great promise in boosting the energy storage capability for supercapacitors. The emergence of nanoarchitectured current collectors aims to reach their full potentials in charge storage by addressing the challenging issues such as the intrinsically low electrical conductivity, and the sluggish charging–discharging behavior of most pseudocapacitive materials.
