Summary: Defect engineering is being used to modify battery active materials for improved cycling stability of electrodes. This study quantified vanadium-defective clusters in the V2O3 lattice and found that the defects lead to favorable sites for reversible Zn-ion storage in aqueous Zn coin cell configuration, resulting in 81% capacity retention after 30,000 cycles at 5 A g(-1). The findings suggest that aqueous Zn metal batteries with vanadium-defective V2O3 cathodes could be a promising system for high-power electrochemical energy storage.

Summary: Vanadium sesquioxide (V2O3) embedded in carbon nanofibers (V2O3@C NFs) was developed as a flexible and binder-free cathode material for aqueous zinc-ion batteries (AZIBs), exhibiting high initial capacity, excellent cycling stability, and enhanced rate capability. The unique structure of V2O3@C NFs, including nano-sized V2O3 crystals with a tunnel-like 3D phase structure uniformly distributed in N-doped carbon NFs, contributes to its superior electrochemical performance. The theoretical simulations based on first-principles calculations provide insights into efficient zinc storage mechanism, and the practical application potential of V2O3@C NFs as a cathode material for AZIBs was demonstrated through assembly of a full battery.

Summary: Aqueous zinc-ion batteries (AZIBs) are favored for new-generation energy-storing devices due to their low cost, safety, environmental friendliness, and abundant resources. However, AZIBs often underperform in long-life cycling and high-rate conditions due to limited cathode options. To address this issue, a facile evaporation-induced self-assembly technique was proposed to prepare V2O3@carbonized dictyophora (V2O3@CD) composites using inexpensive biomass dictyophora as carbon sources and NH4VO3 as metal sources. The V2O3@CD exhibited high initial discharge capacity and excellent long-cycle durability in AZIBs, thanks to the formation of a porous carbonized dictyophora frame that ensured efficient electron transport and prevented V2O3 from losing electrical contact. This strategy of using metal-oxide-filled carbonized biomass materials provides insights into developing high-performance AZIBs and other energy storage devices with broad applications.

Summary: Antimony-doped tin oxide (ATO) was prepared by co-precipitation method and used for surface modification of spherical zinc oxide to obtain ZnO@ATO composites with excellent properties. As an anode material for zinc-nickel batteries, ZnO@ATO exhibits superior performance in terms of cycle life and stability, attributed to the optimization effect of ATO on the ZnO electrode. ATO enhances conductivity, specific surface area, electron transfer, and current density homogeneity, effectively suppressing polarization effect in electrode reaction. Electrochemical test results show that ZnO@ATO maintains a discharge specific capacity of 561.8 mAh•g(-1) after 1950 cycles, which is 96% of the initial discharge specific capacity (583.6 mAh•g(-1)), demonstrating excellent cycle life and capacity retention.
