This tutorial review provides a brief summary of recent research progress on carbon-based electrode materials for supercapacitors, as well as the importance of electrolytes in the development of supercapacitor technology. The basic principles of supercapacitors, the characteristics and performances of various nanostructured carbon-based electrode materials are discussed. Aqueous and non-aqueous electrolyte solutions used in supercapacitors are compared. The trend on future development of high-power and high-energy supercapacitors is analyzed.read more

Three-dimensional porous graphene-like sheets synthesized from biocarbon via low-temperature graphitization for a supercapacitor
TL;DR: In this article, three-dimensional porous graphene-like sheets (3DPGLS) were directly synthesized from biocarbons at 900 °C using Potassium carbonate as a catalyst to release graphite microcrystals from the crosslinked sp3 carbon atoms in the hard carbon phase and subsequently recrystallized them to form graphene layers.
