Abstract:Construction of eco-benign, cost effective, and high-performance supercapacitors with improved electrolytes and hierarchical porous electrodes is necessary for effective energy storage. In this study, a gel type organic redox electrolyte made of polyvinyl alcohol (PVA)-H 2 SO 4 and an organic redox molecule, anthraquinone (PVA-H 2 SO 4 -AQ) was prepared by simple solution casting method, and was used to construct a symmetric supercapacitor (SSC) with a date stone-derived activated carbon (DSAC) having a high B… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
