【Abstract】 Successfully isolated in 2004,graphene was a two-dimentional carbon material consisting of a single layer of carbon atoms. Due to its big specific surface area and high electrical conductivity,graphene has recently attracted increasing attention regarding its potential to serve as an electrode material for CDI. This paper reviews the literature applying graphene or graphene composites(collectively called graphene-based materials) as the CDI electrode materials(published since 2009 when the first relevant paper emerged). Firstly,the fabrication techniques of graphene-based materials were summarized. Then,the values of parameters describing the electrode performance of graphene-based materials were summarized(including specific capacitance,specific surface area,average pore diameter,and electrical conductivity)and comparisons regarding those key parameters were made between different graphene-based materials. Also,the Na Cl electrosorption capacities of the graphene-based materials when applied in CDI were discussed and compared to those of other carbon electrode materials. Finally,prospects for future work on graphene-based materials as a CDI electrode were outlined.更多还原
