Hybrid Electrolyte Enhances Supercapacitance in Vertical Graphene Nanosheets

Supercapacitors can store more energy than and are preferable to batteries because they are able to charge faster, mainly due to the vertical graphene nanosheets that are larger and positioned closer together. Using VGNs as the material for supercapacitor electrodes offers advantages due to their intriguing properties, and those advantages can be enhanced depending on how the material is grown, treated and prepared to work with electrolytes. In this week's Journal of Applied Physics, researchers discuss their work to improve the material's supercapacitance properties.
