Abstract:Ecofriendly supercapacitors (SCs) are fabricated with graphene electrodes printed on recycled‐plastics and utilized seawater as electrolyte. Those devices produced an energy density and capacitance of 50.4 Wh kg−1 and 250.4 F g−1, respectively. Later, a mixture of Bi─Mg─Fe─O (BMO) oxides is added to the SC electrodes and the capacitance of the devices increased up to 209%. Subsequently, SC electrodes are recovered from used/tested devices and utilized as “seed mats” to grow bean plants. For this purpose, pinto… 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.
