Nevertheless, the limited reversibility of the Zn anode and the low coulombic efficiency of the electroplating process limit the application of AZIBs. In this work, pyrrole is employed as a cost-effective electrolyte additive for stabilizing the Zn anode for the first time. By altering the coordination environment of Zn (H<sub>2</sub>O)<sub>6</sub><sup>2+</sup>, chemical and hydrogen evolution corrosion was reduced, and a molecular interface layer was in-situ constructed on the surface of the metal Zn anode, thus effectively inhibiting the corrosion of Zn anode and the growth of dendrites.

Therefore, the electrochemical performance of the metal Zn anode is greatly improved in the pyrrole-based electrolyte. At the current density of 1 mA·cm<sup>−2</sup>, the stable cycle can exceed 1200 h, and the average Coulomb efficiency is as high as 99%.

Here, it is demonstrated that the specific accumulation of oleic acid-modified polyoxovanadates (OPOVs) in adipose tissue leads to the reduction of iron concentrations in adipocytes in mice fed with a high-fat diet (HFD). Conjugation of oleic acids to polyoxovanadates enables tissue-specific depletion of iron from white adipose tissue (WAT) by OPOVs, protecting mice from HFD-induced obesity and obesity-associated metabolic deteriorations. Glucose tolerance and insulin sensitivity are improved in OPOV-treated mice, which demonstrates that the OPOV-induced iron depletion can reverse the metabolic degeneration caused by HFD-induced obesity. Furthermore, a decrease in expression of the marker genes of iron overload suggests the participation of OPOVs in maintaining iron homeostasis and a potential medical application of vanadium clusters in targeting the iron overload caused by obesity.
