“…The crystal phases of MnVOH@PEDOT and MnVOH are analogous to previous reported M x V 2 O 5 ·nH 2 O cathode, such as Zn 0.25 V 2 O 5 ·0.85H 2 O and Ni 0.22 V 2 O 5 ·nH 2 O, indicating that Mn 2+ ‐ions successfully inserted into the V 2 O 5 (Figure 2A). 33,34 The Mn 2+ ‐intercalation process instead of CH 3 COO − was confirmed by similar XRD pattern of MnVOH@PEDOT when replacing Mn(CH 3 COO) 2 ·4H 2 O with MnSO 4 ·H 2 O as raw material in synthesis process (Figure S2). And the pre‐inserted Mn 2+ ‐ions, accompanied by some H 2 O molecules, contributed to a larger interlayer distance of 10.5 Å or 10.8 Å than that of 4.4 Å for pure V 2 O 5 , benefiting to the fast Zn 2+ ‐ions diffusion 35 .…”

Layered vanadium oxides are promising cathode materials for zinc-ion batteries (ZIBs) owing to their high capacity, but the sluggish electron/ion migration kinetics and structural collapse/dissolution severely limit their Zn 2+ -storage performance. Herein, poly (3,4-ethylenedioxythiophene) coated and Mn 2+ -intercalated vanadium oxides with rich oxygen vacancies (MnVOH@PEDOT) are prepared as the cathodes for ZIBs. The PEDOT coating, synergistic with oxygen vacancies, tailors the electron conductivity, and the Mn 2+ -intercalation enlarges the interlayer spacing for rapid Zn 2+ -ions diffusion. In addition, the pre-intercalated Mn 2+ -ions act as "pillars" to stabilize the structure, and the PEDOT coating prevents the direct contact of vanadium oxides with electrolyte to inhibit its dissolution during cycling. Thus, the MnVOH@PEDOT cathode exhibits superior discharge capacity, favorable rate capability (336.0 mAh g À1 at 8 A g À1 ), and satisfying cyclic durability (84.8% capacity retention over 2000 cycles). This work offers a facile and synergistic design strategy for achieving favorable cathodes for ZIBs.

“…The results show that Cu 0.26 V 2 O 5 @C exhibits excellent comprehensive properties because the Cu doping effectively broadens and stabilizes the layered structure of V 2 O 5 to promote the migration of zinc ions, and the carbon matrix improves the conductivity of the composites. In addition, Wei et al Demonstrated that Ni 2+ intercalated layered V 2 O 5 •nH 2 O [60] (Ni 0.22 V 2 O 5 •nH 2 O) (Figure 11e) also has excellent zinc storage capacity. In 2020, Ni intercalated 𝛿-Ni 0.25 V 2 O 5 •nH 2 O [61] (Figure 11f) (c-g) Reproduced with permission.…”

Rechargeable aqueous zinc‐ion batteries (AZIBs) are recognized as one of the most competitive next generation energy storage systems due to the high theoretical capacity (820 mAh g−1), abundant reserves, low expense, and environmental friendliness. However, in comparison to that monovalent ion secondary battery, the multivalent ion rechargeable battery faces larger metal ion sizes and higher charge/discharge number in the electrochemical reaction process, thereby suffering from larger steric resistance and the electrostatic repulsion in the intercalation–deintercalation process. At present, a great deal of research has shown that the guest ion pre‐embedded host structured cathodes can effectively alleviate the above problems and improve the comprehensive performance of aqueous zinc ion battery. In this review, the development of vanadium oxide ion‐intercalated cathode materials in AZIBs is reviewed, mainly including MXV2O5∙nH2O, MXV3O8∙nH2O, MXV6O13∙nH2O, MXV6O16∙nH2O, and MXV10O25∙nH2O type materials. The reaction mechanisms and electrochemical performance of these materials are described, and the future research directions are prospected. It is expected to provide fundamental and engineering guidance for the development of high performance AZIBs cathode materials.
