The development of aqueous zinc-ion batteries (AZIBs) is hindered by dendrites and side reactions, such as interfacial byproducts, corrosion, and hydrogen evolution. The construction of an artificial interface protective layer on the surface of the zinc anode has been extensively researched due to its strong operability and potential for large-scale application. In this study, we have designed an organic hydrophobic hybrid inorganic intercalation composite coating to achieve stable Zn plating/stripping.

Different from lithium-ion storage, VO can provide higher capacity when storing zinc ions, even exceeding its theoretical capacity (323 mAh g), but the specific reason for this unconventional performance in AZIBs is still unclear. The present study proposes a catalytic oxygen evolution reaction (OER) coupled with an interface oxidation mechanism of VO during the initial charging to a high voltage.

Methods: Select 363 natural delivery cases of hospitalized primiparae and divide them randomly into two groups. In the observation group, 182 primiparae used the multifunctional airbag abdominal pressure belt during the second and third stages of labor, whereas the control group of 181 did not use the belt.
