Aqueous zinc-ion batteries (AZIBs) already become a potential candidate for high-efficiency energy storage in view of inherent safety and abundant zinc reserves. Nevertheless, the progress of AZIBs cathode materials with excellent comprehensive performance still retains formidable challenges. Herein, the three-dimensional amorphous vanadium pentoxide@graphene (3D a-V 2 O 5 @graphene) microspheres were prepared and investigated as the cathode material of AZIBs. The amorphous characteristics of a-V 2 O 5 and the threedimensional graphene framework with outstanding conductivity synergistically enabled the 3D a-V 2 O 5 @graphene microspheres to expose more active sites and achieve rapid ion/electron transfer. Consequently, the obtained a-V 2 O 5 @ graphene presented a promising specific capacity of 518 mAh g −1 under 0.5 A g −1 and a stable long-term cycle with an eminent remaining capacity of 177 mAh g −1 over 2000 cycles under 40 A g −1 . Meanwhile, the storage mechanism also was illuminated by various ex situ characterization tests. Hence, this study provides a new viewpoint for the design of advanced AZIBs based on amorphous cathode materials.

“…In addition, carbon/metal dichalcogenides, nitride, and carbide, were also studied. [118,209,210] The purpose of synthesizing these composites aims to break the bottlenecks of the EDL ion storage mechanism in pure carbon. In these composites, the metal compounds dominate the ion storage, whereas carbons only play roles in improving electrical conductivity, cycling stability, etc., which we discussed in the next section.…”

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

“…To date, over 70 kinds of MXene phases have been reported and the number is continuously growing, enabling this class of materials to be promising constitutional substrates for building 2D superlattice structures. [110,156,[158][159][160] Specifically, the extraordinary electric/electrochemical properties of MXenes provide them to be a good platform to develop new 2D MXene-based superlattices for energy storage and conversion, such as multi-low-dimensional GerMXene superlattice heterostructures. [161] Besides the above-mentioned typical classes of 2D superlattice materials, with the development of intercalation and other techniques, 2D superlattices composed of organic molecules have brought into novel inorganic-organic hybrid superlattice structures, such as THAB/In 2 Se 3 , [162] TiS 2 (HA) 0.025 , [163] LDHs/Fe-PP, [164] polyaniline-V 2 O 5 , [165] etc.…”

Exploring low‐cost and high‐efficient electrocatalyst is an exigent task in developing novel sustainable energy conversion systems, such as fuel cells and electrocatalytic fuel generations. 2D materials, specifically 2D superlattice materials focused here, featured highly accessible active areas, high density of active sites, and high compatibility with property‐complementary materials to form heterostructures with desired synergetic effects, have demonstrated to be promising electrocatalysts for boosting the performance of sustainable energy conversion and storage devices. Nevertheless, the reaction kinetics, and in particular, the functional mechanisms of the 2D superlattice‐based catalysts yet remain ambiguous. In this review, based on the recent progress of 2D superlattice materials in electrocatalysis applications, the rational design and fabrication of 2D superlattices are first summarized and the application of 2D superlattices in electrocatalysis is then specifically discussed. Finally, perspectives on the current challenges and the strategies for the future design of 2D superlattice materials are outlined. This review attempts to establish an intrinsic correlation between the 2D superlattice heterostructures and the catalytic properties, so as to provide some insights into developing high‐performance electrocatalysts for next‐generation sustainable energy conversion and storage.
