Electrochemical energy storage foundation construction
Graphene is a flat 2-D honeycomb-shaped monolayer sheet of carbon atoms that is the basic building blocks of other carbon materials as illustrated in Figure 7 (Geim and Novoselov, 2007). ... Actually, Figure 1 illustrates Ragone plots of several well-known electrochemical energy storage devices, including supercapacitors. A trend of diminishing ...
