Design of activated carbon/activated carbon asymmetric capacitors [PDF]
Supercapacitors are energy storage devices that offer a high power density and a low energy density in comparison with batteries. Their limited energy density can be overcome by using asymmetric configuration in mass electrodes, where each electrode ...

Solid asymmetric electrochemical capacitors using proton-conducting polymer electrolytes
Abstract Solid asymmetric electrochemical capacitors (EC) using polyvinyl alcohol (PVA)–heteropoly acid (HPA) electrolytes and RuO 2 –graphite electrodes were developed. The devices were about 0.2 mm thick and had a working voltage window of 0–1.5 V, 50% wider than that of any proton-conducting symmetric EC.

Characterisation of anomalous forces on asymmetric high‐voltage capacitors
In this study, the authors analysed an anomalous force observed in asymmetric capacitors, working in high electric potentials. From a lot of experimental measurements performed in their asymmetric capacitor, they detected real variations of the device inertia. An empirical formula of the developed force according to Clausius–Mossotti relation explained
