Electrochemical energy storage devices can offer a number of great potentials for meeting future energy demands, such as of renewable energy, electric vehicles, portable electronics, that require high energy density, high power density and long cycle life. Among the various electrode materials available for energy storage devices, graphene, a one-atom-thick, two-dimensional sp2 carbon structure, has attracted considerable interest as a next-generation electrode material. This can be attributed to a number of interesting properties of graphene, such as its good mechanical/chemical stability, high electrical/thermal conductivity, and a large surface area due to its high surface-to-volume ratio.[1] The combination of these unique physical and chemical properties means that graphene has significant potential to act as an electrochemically active material for use in energy storage devices such as Li-ion batteries and electrochemical capacitors.[2,3] In this study, we report on the synthesis and electrochemical characterization of nanoperforated graphene-based electrode materials for energy storage applications. More details will be discussed at the meeting.
