“…EG delivered a high capacity of 111 mAh g –1 at a current density of 2000 mA g –1 after 300 cycles and 61.1 mAh g –1 at a ultrahigh current density of 50 000 mA g –1 after 10000 cycles (Figure 10b). [ 124 ] Also, Gao's group [ 126 ] reported EG treated at high temperature as positive electrode for RABs, which delivered the enhanced capacity and rate performance (110 mAh g –1 at 1000 mA g –1 with 18 000 cycles, and 100 mAh g –1 at 5000 mA g –1 with 27 500 cycles). In addition to expanded graphite materials, Zeolite‐templated carbon (ZTC) was reported with an enlarged spacing (1.36 nm) and high surface area (>3500 m 2 g –1 ).…”

such as high working voltage, large energy density, small volume, lightweight, and environmental friendliness. However, the limited Li and Co resources will increase the LIB cost, and the overcharge and/or overdischarge put it at risk of explosion and combustion, which can restrict its further application. [1,2] From the perspective of a sustainable development strategy, it is imperative to develop a chemical power supply system with low cost, high safety, long cycle life, and high energy density by utilizing elements with richer earth reserves. [3] In recent years, research on aluminumion batteries has provided new insight to solve the abovementioned issues. Compared with traditional secondary batteries, rechargeable aluminum batteries (RABs) possess the advantages of low cost, good safety, large capacity, long cycle life, wide temperature performance, and diverse chemical components and phases, which have promising applications in commercial energy storage systems. [4][5][6][7][8][9] The development of RABs not only helps to solve the problem of excess bulk metal aluminum, [10] but also is of great significance to future energy storage systems. Currently, nonaqueous RABbased ionic liquids, molten salts, quasi-solid and solid electrolytes have attracted substantial attention and have made great progresses. [11][12][13][14][15][16] Compared with advanced commercial LIBs, current nonaqueous RABs are still in their infancy, and their true potential remains to be explored. To realize large-scale application, more efforts have been made, such as clarifying the reaction mechanisms and developing high-performance positive materials. As a series of novel positive materials have achieved significant breakthroughs, nonaqueous RABs have gained more attention. Different from the traditional single ion rocking-chair battery (taking LIBs as a typical representative), nonaqueous RABs have more than two kinds of active species participating in the reaction processes of the positive electrode and negative electrode. In AlCl 3 -based acidic electrolytes, the anions are mainly AlCl 4 − and Al 2 Cl 7 −. With an increase in the AlCl 3 molar ratio, Al 2 Cl 7 −The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smll.202201362.

The rising energy crisis and environmental concerns caused by fossil fuels have accelerated the deployment of renewable and sustainable energy sources and storage systems. As a result of immense progress in the field, cost-effective, high-performance, and long-life rechargeable batteries are imperative to meet the current and future demands for sustainable energy sources. Currently, lithium-ion batteries are widely used, but limited lithium (Li) resources have caused price spikes, threatening progress toward cleaner energy sources. Therefore, post-Li, batteries that utilize highly abundant materials leading to cost-effective energy storage solutions while offering desirable performance characteristics are urgently needed. Aluminum-ion battery (AIB) is an attractive concept that uses highly abundant aluminum while offering a high theoretical gravimetric and volumetric capacity of 2980 mAh g À 1 and 8046 mAh cm À 3 , respectively. As a result, intensified efforts have been made in recent years to utilize numerous electrolytes, anodes, and cathode materials to improve the electrochemical performance of AIBs, and potentially create high-performance, low-cost, and safe energy storage devices. Herein, recent progress in the electrolyte, anode, and cathode active materials and their utilization in AIBs and their related characteristics are summarized. Finally, the main challenges facing AIBs along with future directions are highlighted.

“…Among the various cathode materials that have been reported so far, graphitebased carbon materials have a high working voltage (∼1.8-2.0 V) and can achieve stability for thousands of cycles, but the capacity is relatively limited (∼60-150 mA h g −1 ) and difficult to further improve. [3][4][5][6][7] Chalcogens (S/Se/Te) have extremely high theoretical capacities and are important candidates for improving the energy density of RAIBs. However, various difficulties are also faced in the research of elemental cathode materials.…”
