Graphene-based supercapacitors are advanced energy storage devices that utilize graphene as an active electrode material instead of carbon. Graphene offers extremely high theoretical specific surface area and electrical conductivity which allows supercapacitors built with graphene electrodes to deliver high energy densities comparable to lithium-ion batteries. Graphene allows supercap... https://www.zupyak.com/p/4472242/t/the-graphene-based-supercapacitors-market-is-anticipated-to-witness-high-growth-owing-to-rise-in-demand-for-renewable-energy-storage
