Capacitive deionization (CDI), which is based on ion electrosorption on the surface of electrically charged electrodes, has attracted widespread attention as a novel, cost-effective and environment-friendly desalination technology. Carbon materials are widely used as CDI electrodes due to their high specific surface area (SSA), superior conductivity, and better stability. Many research efforts have been made to further enhance the CDI performance of carbon materials. In this review, the performance-enhancing strategies of various carbon materials including activated carbon, porous carbon, carbon aerogels, carbon nanotubes and graphene are systematically presented. We also explain the significance of the development of CDI technology and identify where further work is urgently required and where challenges are still faced.
电容去离子化（CDI）基于离子在带电电极表面的电吸附作用，作为一种新型、经济高效且环境友好的脱盐技术已引起广泛关注。碳材料因其高比表面积（SSA）、优异的导电性和更好的稳定性而被广泛用作CDI电极。人们已经进行了许多研究工作来进一步提高碳材料的CDI性能。在这篇综述中，系统地介绍了包括活性炭、多孔碳、碳气凝胶、碳纳米管和石墨烯在内的各种碳材料的性能增强策略。我们还解释了CDI技术发展的意义，并指出迫切需要进一步开展工作的方向以及仍然面临的挑战。
