Graphene‐Based Energy Devices

Graphene Nanocomposite Materials for Supercapacitor Electrodes

“…The history of graphene and its relatives, with attention to the specific properties, advantages, as well as disadvantages for various possible applications beyond electrochemical energy storage and conversion, has been reviewed repeatedly [4][5][6][7][8][14][15][16][17][18]38]. In reviews, the use of graphene in numerous applications beyond energy storage and electrochemistry has been addressed [39][40][41][42][43].…”

“…Following the enthusiastic reports about the properties of graphene and later of graphene-related materials like graphene oxide (GO), reduced graphene oxide (rGO) and further materials like crumpled graphene [1][2][3][4], suggestions of their use in electrochemistrywherein carbon in its numerous forms has been a popular material for electrodes or as components of electrode materials has been around for decades-and in particular in devices for electrochemical energy conversion and storage (EES) [5,6] followed. These suggestions later included their use in supercapacitors [5,[7][8][9][10][11][12][13][14][15][16][17][18]. As an electrode material in the latter application (as well as in battery applications), materials should meet some general requirements:…”
