“…Coupled with other cathode materials (e.g., carbon, NASICON, and others), the desalination capacity can range from 17-115 mg g −1 . [129,[254][255][256][257][258][259] Their performance comparison with other materials in CDI in different NaCl concentration solutions is plotted in Figure 16. The SAC for most carbon-based materials is close to 20 mg g −1 .…”

freshwater storage. [6,7] Figure 1 shows the annual average monthly blue water (fresh surface water and groundwater) scarcity.Regions like Australia, central America, North China, and North Africa face the highest freshwater scarcity. Two-thirds of the global population suffers from severe freshwater scarcity at least 1 month of the year, and half a billion people worldwide face severe freshwater scarcity all year around. [8] This issue will intensify in the future due to climate change and evergrowing water consumption.The earth's climate and the terrestrial water cycle have a close and complex relationship. [9] Climate change is causing parts of the water cycle to speed up as warming temperatures increase the water evaporation rate. Scientific evidence shows that global warming is now unequivocal. [10] Greenhouse gas emissions have steeply increased, directly affecting terrestrial water budgets. For example, water decreases have already been observed in western Africa, southwestern Australia, the Yellow River basin in China, and the Pacific Northwest of the United States of America. Such decreases affect freshwater availability directly. [8,11] In addition to the negative effects of climate change on freshwater access, the higher water consumption of our world population and economic activities are causing great additional freshwater stress. For example, agriculture consumes 50-60%, industries use 5-10%, and 10-20% is used for urban purposes. [12] Further, many of these activities may lead to polluted water, decreasing the available clean and freshwater. For these reasons, the United Nations declared freshwater as one of the many global challenges that need immediate action for sustainable development. [13] Depending on the total mass of dissolved solids in water, natural water is classified into brine water (>50 g L −1 ), saline water (30-50 g L −1 ), brackish water (0.5-30 g L −1 ), and freshwater (0-0.5 g L −1 ). [14] According to the World Health Organization, drinkable water should contain <0.25 g L −1 of salt, and the limitation on agriculture irrigation is 2 g L −1 . [15,16] There is a need to obtain freshwater by leveraging the tremendous amount of non-fresh water that can be made useable. This can be done by extracting undesirable ions from existing water in a desalination process. This process needs to be energy-efficient and cheap for sustainability and affordability. Water desalination is a promising and practical approach to maintaining an adequate potable water supply. [17,18] Capacitive deionization (CDI) is burgeoning as a cost-effective and energy-efficient

“…The coupling of inorganic compounds and organic components has been a common method for improving the performance of CDI. [280][281][282][283][284] For example, the composite material is constructed of polyoxymethylene and the conductive polymer is based on pseudo-capacitance characteristics and is an ideal choice for desalination of MCDI electrodes (Fig. 11f and g).…”
