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.

“…To make EES devices practically feasible, it is highly desirable to develop a suitable cathode material to accommodate the large number of charges from the electrolyte. Several materials, such as V 2 O 5 , , TiO 2 , polyaniline (PANI), MoO 3 , , CuHCF, etc., have been explored as cathode materials for Al-ion energy storage. V 2 O 5 -based EES devices change color from green to yellow, while TiO 2 -based EES devices change color from transparent to blue.…”

Aqueous-based electrochromic batteries have significant potential for use in color indicator energy storage, including energy-efficient buildings and wearable devices with visible energy level performance. While many materials have the ability to change color upon ion intercalation, they often have low optical contrasts and capacities. To address these issues, multivalent ions can provide a solution by providing multiple electrons, resulting in a higher optical contrast and capacity. Herein, we propose an Al-ion electrochromic battery with a unique design, utilizing WO 3 as the cathode material, Al metal as the anode, and AlCl 3 as the aqueous electrolyte. Ex situ X-ray diffraction results reveal that the peak position and interlayer spacing of the optimized WO 3 porous thin film (∼170 nm) change during Al-ion intercalation and deintercalation, indicating the high structural stability of the optimized WO 3 electrode. A double cathode-electrochromic battery (DC-EES) device consisting of two cathodes on either side of an Al metal film anode was fabricated and demonstrated superior electrochemical performance due to its increased active surface area and open circuit potential. The device exhibited an open circuit potential of ∼1.2 V and a capacity of ∼155 mAh/ m 2 at 0.5 A/m 2 , which are sufficient values for powering an electronic device. Additionally, the developed device exhibited excellent electrochromic behavior upon discharge with an optical contrast of 68% (transparent and blue). These results show the great potential of Al-ion electrochromic batteries as a cost-effective and high-safety material for applications in smart windows and energy storage displays in modern infrastructures.
