摘要
介绍了电容去离子技术(CDI)的工作原理、发展历程,以及实际装置中的常见脱盐模型和CDI技术的应用现状;叙述了CDI电极材料研究发展的前沿动态,归纳了CDI技术对其所使用电极材料的性能要求。综合考虑CDI工作原理和影响因素,认为现阶段提高其脱盐效果的关键在于电极材料性能;而目前的CDI研究,在模拟盐水、材料赝电容、CDI技术应用局限性等方面还存在问题。未来CDI技术在能量回收利用、与绿色能源结合使用,或进行小型化便携式发展这些方面,将具有非常好的发展优势和前景。
An overview of CDI technology including its operating mechanism, development history. The classical models of CDI apparatus geometries and the applications of CDI are also introduced briefly. The advancement of electrode materials in recent years is summarized particularly, the requirements of material properties for the use of CDI electrode are summarized. In consideration of the working mechanism and affecting factors of CDI, the present key factor that influences desalination performance is the material used as electrode. There are problems such as simulated saline, material specific capacitive and the limitation of the application of CDI technology in the current CDI studies, while the future CDI technology including energy recovery, the combination of green powers, or the development towards miniaturization and portability, has great competitiveness and prospect.
