Manganese-based cathode materials for aqueous rechargeable zinc-ion batteries: recent advance and future prospects

An anthraquinone-based covalent organic framework for highly reversible aqueous zinc-ion battery cathodes

“…[1][2][3] On this basis, aqueous rechargeable zinc-ion batteries (ZIBs) are gradually emerging to become highly efficient and competitive energy storage systems based on their low redox potential (−0.76 V vs. SHE), intrinsic safety, resource richness, and high theoretical capacity (820 mA h g −1 ). [4][5][6] To further drive the advancement of aqueous ZIBs, appropriate cathode materials have been extensively explored and researched, [7][8][9] for instance, manganese-based oxides, [10][11][12][13] Prussian blue analogs, [14][15][16] vanadium-based compounds, [17][18][19][20] molybdenum-based oxides/suldes, 21 and organic compounds. 22 Among these, organic materials have triggered a research boom in aqueous ZIBs in terms of their lightweight, lower toxicity, and sustainability.…”

Ostwald ripening mechanism-derived MnOOH induces lattice oxygen escape for efficient aqueous MnO2–Zn batteries

“…51 However, a series of problems, such as the irreversible phase transition and collapse of the structure, lead to rapid decline in battery capacity and unsatisfactory cycle ability, which will seriously hinder their large-scale commercial application. [52][53][54] Therefore, researchers have proposed various strategies to address these challenges, including hybridization with carbon or other conductive materials to enhance the conductivity of MnO 2 , doping with different elements to stabilize the structure and suppression of disproportionation a CAS Key Laboratory of Design and Assembly of Functional Nanostructures, Fujian Provincial Key Laboratory of Nanomaterials, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Fuzhou 350002, China.

Zinc-ion hybrid supercapacitor-batteries with a leaf-like ZIF-L/MgNiO2 micro-sphere composite and a Zn2+/sulfonated poly(ether ether ketone) gel

“…Transition metal oxides and metal-organic frameworks (MOFs) are widely used as cathodes in Zn-ion storage systems. [28][29][30] They typically store and release charge by undergoing redox reactions at the metal nodes or sites. In this study, a dual strategy to improve cycling lifespan and capacity is implemented by using a composite of a Zn-MOF (ZIF-L, where ZIF is a zeolitic imidazole framework) and a mixed metal oxide (MgNiO 2 ) as the cathode.…”
