Zinc-Ion Hybrid Supercapacitors In article number 2300630, Bon-Ryul Koo, Geon-Hyoung An, and co-workers present a novel design for high-performance zinc-ion hybrid supercapacitors. They achieve this by introducing multifunctional VOSO4 additives, which can spontaneously generate zinc vanadium hydrate layer with oxygen vacancies on the surface of electrode. This study provides new strategy addit...

The very fast evolution in wearable electronics drives the need for energy storage micro-devices, which have to be flexible. Micro-supercapacitors are of high interest because their power density, long cycle lifetime and charge discharge. Recent developments on micro-supercapacitors focus improving overall electrochemical performance, mechanical properties. In this review, different types confi...

Aqueous supercapacitors (SCs) are highly desirable as the next generation of energy storage devices, holding promise being environmentally friendly and free safety concerns. However, their low water-splitting voltage prevents practical applications. Here, we utilize a dielectric-polymer-coated, hierarchically structured carbon electrode to prepare dielectric-electrolyte SC (DESC), which exhibit...
