Charge Storage Capability of Tunnel MnO2 and Alkaline Layered Na-MnO2 as Anode Material for Aqueous Asymmetry Supercapacitor

Charge Storage Capability of Tunnel MnO2 and Alkaline Layered Na-MnO2 as Anode Material for Aqueous Asymmetry Supercapacitor

We report here the charge storage capability of two different crystallographic structures of MnO2; tunnel and alkaline layered Na-MnO2 as a potential non-carbon based, high working potential electrode for supercapacitor applications. A hydrothermal route was used to prepare both materials. Further,...
