“…[5] Various aqueous batteries, such as Fe-Cr, Pb acid, Zn ion, Zn-Ce, and Zn-Br batteries (ZBBs), are attracting interest as alternatives to LIBs because they use earth-abundant elements and offer better safety. [6][7][8][9][10][11] ZBB was proposed in 1885 and first commercialized in the 1970s by Exxon. [12] ZBBs use lowcost electrode materials (Zn and carbon) and have a high theoretical energy density of 428 Wh kg −1 , comparable to LIBs.…”

Zinc‐bromine batteries (ZBBs) have recently gained significant attention as inexpensive and safer alternatives to potentially flammable lithium‐ion batteries. Zn metal is relatively stable in aqueous electrolytes, making ZBBs safer and easier to handle. However, Zn metal anodes are still affected by several issues, including dendrite growth, Zn dissolution, and the crossover of Br species from cathodes to corrode anodes, resulting in self‐discharge and fast performance fading. Similarly, Br2 undergoes sluggish redox reactions on cathodes, which brings several issues such as poor reaction kinetics, the highly corrosive nature of Br species leading to corrosion of separators and poisoning of anodes, and the volatile nature of Br species causing increased internal pressures, etc. These issues are compounded in flowless ZBB configuration as no fresh electrolyte is available to provide extra/fresh reaction species. In this review, the factors controlling the performance of ZBBs in flow and flowless configurations are thoroughly reviewed, along with the status of ZBBs in the commercial sector. The review also summarizes various novel methodologies to mitigate these challenges and presents research areas for future studies. In summary, this review will offer a perspective on the historical evolution, recent advancements, and prospects of ZBBs.

“…However, the manganese dissolution and the irreversible structural degradation faced by manganese-based cathode materials in the electrochemical reaction make the electrochemical performance far from satisfactory. [26,27] To solve the above problems, a series of effective strategies have been gradually proposed, such as structural design, [28] complex construction, [29] intercalation tactics, [30] defect engineering, [31] and interfacial modification. [32] Given its role in modifying the surface chemistry and geometric morphology of oxides, oxygen defects are considered as an effective and feasible strategy for the development of high-performance ZIBs.…”

Manganese‐based material is a prospective cathode material for aqueous zinc ion batteries (ZIBs) by virtue of its high theoretical capacity, high operating voltage, and low price. However, the manganese dissolution during the electrochemical reaction causes its electrochemical cycling stability to be undesirable. In this work, heterointerface engineering‐induced oxygen defects are introduced into heterostructure MnO2 (δa‐MnO2) by in situ electrochemical activation to inhibit manganese dissolution for aqueous zinc ion batteries. Meanwhile, the heterointerface between the disordered amorphous and the crystalline MnO2 of δa‐MnO2 is decisive for the formation of oxygen defects. And the experimental results indicate that the manganese dissolution of δa‐MnO2 is considerably inhibited during the charge/discharge cycle. Theoretical analysis indicates that the oxygen defect regulates the electronic and band structure and the Mn‐O bonding state of the electrode material, thereby promoting electron transport kinetics as well as inhibiting Mn dissolution. Consequently, the capacity of δa‐MnO2 does not degrade after 100 cycles at a current density of 0.5 A g−1 and also 91% capacity retention after 500 cycles at 1 A g−1. This study provides a promising insight into the development of high‐performance manganese‐based cathode materials through a facile and low‐cost strategy.

Photoresponsive batteries are an innovative technology that combines conversion and storage of solar energy, providing a potential solution for large‐scale utilization of solar energy while reducing the reliance on traditional energy storage devices to meet the growing demand for energy. In search of more resource‐saving alternatives to lithium‐ion batteries, researchers are turning to zinc, which is abundant and environmentally friendly due to its recyclability. Zinc batteries offer high energy density and aqueous stability, making them a popular choice among researchers. This review summarizes the recent progress in photoresponsive zinc‐based batteries. First, the photoresponsive zinc‐based batteries are categorized into two groups: photoresponsive zinc‐ion batteries and photoresponsive zinc–air batteries. The discussion then focuses on various photoelectrode designs, including some interesting strategies. Finally, the technical challenges associated with photoresponsive zinc‐based batteries are summarized and discussed, and future research directions are proposed.
