Summary: The electrochemical performance and reaction mechanism of orthorhombic V2O5 in 1 M ZnSO4 aqueous electrolyte were studied. V2O5 nanowires showed an initial discharge and charge capacity at a current density of 50 mA g(-1), but experienced quick capacity fading during cycling. Interestingly, V2O5 demonstrated a higher discharge capacity at 200 mA g(-1) after 10 cycles, possibly due to different activation processes and degrees of side reactions under different current densities.

Summary: In situ electrochemical activation is used to improve the electrochemical performance of electrode materials. By inducing Mn-defect, the MnOx/Co3O4 heterointerface is activated as a high electrochemically active cathode for aqueous zinc-ion batteries (ZIBs). The heterointerfaces between different phases reduce energy barrier for ion migration and facilitate electron/ion diffusion, resulting in outstanding fast charging performance and high energy density for MnOx/Co3O4 in ZIBs.

Summary: This study highlights an unreported in-situ electrochemical amorphization mechanism to improve the kinetics of electrodes in aqueous zinc-ion batteries. Through various characterizations and simulations, it is revealed that the reconstruction of long-range ordered ZnV2O4 crystalline to short-range ordered Zn0.44V2O4 electrode leads to improved active sites, diffusion path, and zinc ions capture ability. The reconstructed amorphous electrodes exhibit ultrahigh rate capability and good cycle performance, even at cryogenic conditions. This in-situ electrochemical amorphization mechanism provides new insights into high-performance aqueous zinc-ion batteries.

Summary: In this study, a new cathode material for aqueous zinc-ion batteries (ZIBs) was reported, namely MIL-88B(V)@rGO composites. The cathode was composed of MIL-88B(V) nanorods anchored on reduced graphene oxide (rGO) sheets. During the initial charge/discharge process, the cathode underwent an in situ irreversible transformation from MIL-88B(V) to amorphous V2O5, which acted as the active site for Zn2+ insertion/extraction. The hierarchical structure of the composites and the amorphous V2O5 provided abundant channels and active sites for Zn2+ diffusion and adsorption. The rGO sheets functioned to improve the conductivity and reduce the Zn2+ migration energy barrier. The MIL-88B(V)@rGO cathode exhibited an ultrahigh reversible capacity and good rate performance, surpassing the reported metal-organic frameworks (MOFs) cathodes.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
