“…However, the large electrostatic forces between the divalent zinc ions and the host lattice, coupled with the large radius of the hydrated zinc ions, make the selection of a suitable cathode material a difficult task. Until now, cathode materials for ZIBs are extensively investigated including vanadium-based materials, − manganese-based oxides, − Prussian blue analogs, − MoS 2 − materials, and other emerging materials. For Prussian blue analogs, the low specific capacity, crystal defects, and low conductivity restrict their development. , Manganese-based oxides are prone to generate disproportionation reactions and structural collapse during cycling, in spite of their abundant and safe nature, which significantly affects the electrochemical performance of AZIBs .…”

Environmental concerns promote the development of sustainable energy storage devices. Resource-rich vanadium oxides with easily adjustable valence still exhibit unsatisfactory electrochemical performance stemming from poor electrical conductivity and friable structure as aqueous zinc-ion battery (AZIB) cathodes. Herein, vanadium oxide (VO-300) enriched with oxygen vacancies is acquired via a convenient solvothermal method in combination with subsequent heat treatment, which exhibits a remarkable rate performance of 411.98 mAh•g −1 , and an excellent cycling life for 1500 cycles with 92.8% retention at 10 A•g −1 . The enhanced electrochemical performances of VO-300 can be attributed to more oxygen vacancies, which provide more active sites for zinc-ion storage, expand layer spacing, and increase the conductivity of V 2 O 5 . More pivotal, the activation phenomenon is analyzed, and a two-carrier conversion insertion mechanism of H + domination to Zn 2+ domination is proposed. Based on this mechanism, the V 2 O 5 is transformed into Zn x V 2 O 5 •nH 2 O as an active material for subsequent zinc-ion storage, leading to faster electrochemical kinetics. This work not only demonstrates the potential application of V 2 O 5 as a zinc-ion cathode but also provides new insights into the zinc-ion storage mechanism.

“…Mn 3 O 4 is a type of spinel-structured Mn 2+ [Mn 3+ ]O 4 , where Mn 2+ and Mn 3+ are distributed at different lattice positions. Therefore, Mn 3 O 4 could be expressed in the form of MnO•Mn 2 O 3 [23]. As an important industrial raw material, Mn 3 O 4 has extremely wide applications; it is widely used in industries such as soft magnetic materials, supercapacitors, new energy materials, and pigments [24,25].…”

The structure of Mn3O4 with an octahedron structure was similar to that of LiMn2O4, and the lithium manganate prepared with it had good electrochemical performance. During the preparation of octahedron Mn3O4, the effects of the pH regulator, temperature, and reaction pH on its morphology, specific surface area, and other properties were studied in this paper. LiMn2O4 was prepared from Octahedron Mn3O4 obtained by using better technology. The effects of calcination time and temperature on the physicochemical and electrochemical properties of LiMn2O4 were studied. The research results indicated that the optimal synthesis conditions for Mn3O4 were as follows: ammonia water was used as a pH regulator and complexing agent, reaction pH was 8, reaction temperature was 80 °C, reaction time was 12 h, and oxygen flow rate was 3 L∙min−1. The LiMn2O4 synthesized had a good octahedron morphology when the calcination temperature was 800 °C and the calcination time was 10 h. The first discharge-specific capacity was 121.9 mAh∙g−1 at a current density of 0.2 C, the discharge-specific capacity was 114.1 mAh∙g−1 after 100 cycles, and the capacity retention rate was 93.6%. Therefore, the lithium manganate prepared by using octahedron manganous oxide had good electrochemical reversibility and a good application prospect.
