“…Considering the theoretical capacity of LDHs (∼200 mAh g –1 ) and the actual capacities measured between different voltage ranges, the predominate performances of CoFe–Cl-LDH/CNT for electrochemical Cl – storage in a neutral NaCl electrolyte (Figure S4) are superior to those reported and even fairly more superb than those using acidic electrolytes (pH = 2) (Table ). − Consequently, the CoFe–Cl-LDH/CNT anode holds the potential to accommodate and free Cl – repeatedly in neutral water-based electrolytes, offering a novel research perspective on electrode materials for high-performance aqueous energy storage.…”

“…It is well-known that the aqueous electrolyte containing Cl – (e.g., NaCl solution, seawater) is cleaner and safer than nonaqueous electrolytes in nature, ,− resulting in the fabrication of CIBs globally with more green and less pollution. Up to now, despite the ease of manufacture and high theoretical power density (low solvation and viscosity lead to a fast mass diffusion) of aqueous medium, only very few materials (e.g., BiOCl/Bi, AgCl/Ag, and Sb 4 O 5 Cl 2 /Sb) can be applied for ACIBs with the still unsatisfactory electrochemical performance (35 to 95 mAh g –1 ). − Besides, most of these ACIBs were constructed using acidic electrolytes (pH = 2), which will corrode the metal components in batteries and be harmful to the environment. Obviously, neutral aqueous electrolytes are not only easy to access but also have few hazards to the metal components, environment, and human body.…”

Aqueous chloride-ion batteries (ACIBs) with environmental friendliness and high safety hold great potential to fulfill the green energy demand for ocean desalination. Herein, for the first time, a composite consisting of Cl − -intercalated CoFe layered double hydroxides (CoFe−Cl-LDH) crosslinked with CNTs (CoFe−Cl-LDH/CNT) is synthesized and demonstrated to be a novel high-performance anode for ACIBs in a neutral NaCl aqueous solution. While exhibiting a high initial capacity of ∼190 mAh g −1 at 200 mA g −1 , CoFe− Cl-LDH/CNT is capable of delivering a reversible capacity of ∼125 mAh g −1 after 200 cycles. At a high current density of 400 mA g −1 , it still holds a capacity of ∼120 mAh g −1 . The excellent Cl − storage performance can be contributed to the unique topochemical transformation feature that reverses intercalation/deintercalation of Cl − along with valence changes of Co 2+ /Co 3+ and Fe 2+ /Fe 3+ during charge/discharge and the improved electronic conductivity by hybridizing with CNTs. It is interesting that the invertible insertion/extraction of interlayer H 2 O was discovered, which could be beneficial to the capacity after cycles to a certain extent. The Cl − -intercalated LDH material declared in this work shows its feasibility on Cl − capture/ release in aqueous anion-type batteries and provides a new opportunity for future development of ACIBs or aqueous desalination technology.

“…However, the dissolution of metal chlorides in both aqueous and ionic liquid electrolytes often lead to rapid capacity fading. [5,[10][11][12] As a result, researchers shift their focus towards electrode materials based on metal oxychlorides, including BiOCl, [13] FeOCl, [8] Sb 4 O 5 Cl 2 , [10,14] and VOCl.

Anode materials based on metal oxychlorides hold promise in addressing electrode dissolution challenges in aqueous‐based chloride ion batteries (CIBs). However, their structural instability following chloride ion deintercalation can lead to rapid degradation and capacity fading. This paper investigates a cobalt‐doped Sb4O5Cl2‐graphene (Co‐Sb4O5Cl2@GO) composite anode for aqueous‐based CIBs. It exhibits significantly enhanced discharge capacity of 82.3 mAh g‐1 after 200 cycles at 0.3 A g‐1; while, the undoped comparison is only 23.5 mAh g‐1 in the same condition. It also demonstrated with a long‐term capacity retention of 72.8% after 1000 cycles (65.5 mAh g‐1) and a favorable rate performance of 25 mAh g‐1 at a high current density of 2 A g‐1. Undertaken comprehensive studies via in‐situ experiments and DFT calculations, the cobalt (Co) dopant is demonstrated as the crucial role to enhance the lifetime of Sb4O5Cl2‐based anodes. It is found that, the Co dopant improves electronic conductivity and the diffusion of chloride ions beside increases the structural stability of Sb4O5Cl2 crystal. Thus, this element doping strategy holds promise for advancing the field of Sb4O5Cl2‐based anodes for aqueous‐based CIBs，and insights gain from this study also offer valuable knowledge to develop high‐performance electrode materials for electrochemical deionization.

“…Considering the above bottlenecks, LIBs are not available as energy storage systems at the grid level [ 9 ]. Therefore, researchers focus on developing aqueous mental/non-mental ion batteries (Na + [ 10 ], K + [ 11 ], Zn 2+ [ 12 ], Mg 2+ [ 13 ], H + [ 14 ], Cl − [ 15 ], etc.) due to their higher safety and lower cost in meeting the ever-growing demands of the energy industry.…”

Aqueous zinc-ion batteries (AZIBs) are promising for large-scale energy storage systems due to their high safety, large capacity, cost-effectiveness, and environmental friendliness. However, their commercialization is currently hindered by several challenging issues, including cathode degradation and zinc dendrite growth. Recently, metal-organic frameworks (MOFs) and their derivatives have gained significant attention and are widely used in AZIBs due to their highly porous structures, large specific surface area, and ability to design frameworks for Zn2+ shuttle. Based on preceding contributions, this review aims to generalize two design principles for MOF-based materials in AZIBs: cathode preparation and anode protection. For cathode preparation, we mainly introduce novel MOF-based electrode materials such as pure MOFs, porous carbon materials, metal oxides, and their compounds, focusing on the analysis of the specific capacity of AZIBs. For anode protection, we systematically analyze MOF-based materials used as 3D Zn architecture, solid electrolyte interfaces, novel separators, and solid-state electrolytes, highlighting the improvement in the cyclic stability of Zn anodes. Finally, we propose the future development of MOF-based materials in AZIBs. Our work can give some clues for raising the practical application level of aqueous ZIBs.
