Reaction mechanisms and optimization strategies of manganese-based materials for aqueous zinc batteries

The origin of capacity fluctuation and rescue of dead Mn-based Zn–ion batteries: a Mn-based competitive capacity evolution protocol

“…Thereinto, d-phase MnO 2 with a peculiar layered structure, compared with the channel-like structure, is theoretically more reliable for the storage and release of ions, which is supposed to be more suitable for Zn 2+ a College of Physics, the State Key Laboratory of Inorganic Synthesis and insertion/extraction and high-efficiency electrochemical kinetics. [13][14][15][16][17][18] However, in practice, the desired charge storage advantages of the layered structure have not been materialized, which instead embody low specific capacity and poor structural stability. [18][19][20][21] Dissolution of manganese oxide in the discharge/charge process has been considered to be another critical factor for the unsatisfactory electrochemical performance of ZIBs.…”

Strategies of regulating Zn2+solvation structures for dendrite-free and side reaction-suppressed zinc-ion batteries

“…16–22 In a typical prototype, ZIBs consist of zinc metal anodes, (in)organic cathodes, neutral or slightly acidic aqueous electrolytes and separators. Thus far, great research efforts have been devoted to exploring advanced cathode materials for ZIBs and tremendous available materials have been developed for Zn 2+ ion storage such as manganese-based compounds, 23–28 vanadium-based compounds, 29–32 Prussian blue analogues 33,34 and some emerging materials. 18,35–39 In addition, the redox mechanisms of ZIBs have been demonstrated to be based on intercalation-type or conversion-type.…”

Energetic Aqueous Batteries

“…For instance, Han et al systematically introduced the storage mechanisms and optimizing strategies of manganese-based materials for aqueous Zn-ion batteries. [17] Recent advances in the rational design of vanadium-based materials for aqueous Zn-ion batteries were highlighted by Liu and co-workers, focusing on the enhancement of the structural stability, intercalation space, and diffusion ability of Zn 2+ . [18] Wang et al summarized the storage mechanisms of cathode materials and the challenges of using these cathode materials in various electrolytes.…”
