Enhancing the kinetics of vanadium oxides via conducting polymer and metal ions co-intercalation for high-performance aqueous zinc-ions batteries

The Compatibility of COFs Cathode and Optimized Electrolyte for Ultra‐Long Lifetime Rechargeable Aqueous Zinc‐Ion Battery

“…While various inorganic materials like Prussian blue analogs, vanadium-based materials, and manganese-based materials have been explored, their cycling stability often suffers due to volume expansion and crystalline lattice changes during Zn 2 + and H + intercalation. [11][12][13][14][15][16] In contrast, organic cathodes have shown promising results in terms of high cycling stability and capacity retention, as well as barely material dissolution observed in aqueous electrolytes. [17][18][19][20][21] This paves the way for further research into organic materials for RAZIBs.…”

Promoting Desolvation by Hydrophobic and Zincophilic Adsorption Layer To Achieve Stable Zn Anodes at Low Temperature

“…In recent years, aqueous Zn-based energy storage devices are expected to become a key technology for the next generation of sustainable electrochemical energy storage, due to their availability of materials, low cost, and high safety. − In addition, Zn metal has advantages of having high theoretical specific capacity (820 mAh g –1 and 5855 mAh cm –3 ), being nonhazardous, and being easy to produce and store. − However, Zn-based energy storage is limited by dendrite growth on the surface of Zn anode, hydrogen evolution reaction (HER) and surface corrosion, resulting in a poor reversibility, which is more serious at higher current densities. − More importantly, due to the slow reaction kinetics under the conditions of zero temperature, the Zn-based energy storage cannot play a role in normal electrochemical performance, which limits its practical application. − …”

Synergistic zinc-ion storage enabled by Cu ion in anthraquinone-preinserted vanadate: structural integrity and H+-promoted reversible phase conversion

“…The intercalants can also be organic molecules; however, mainly protonated organic amines have been investigated as organic molecules. [20][21][22][23][24] For example, Ma et al introduced ethylenediamine in V 7 O 16 , which provided a high specific capacity and surprising longterm cyclic stability in Zn 2+ storage. 20 Based on this, we considered that redox-active organic species such as 2-methylanthraquinone (denoted as 2-M-AQ) can also be employed as lamellar pillars between the V-O-V layers to expand the interlayer distance.…”
