which produced a Cu–Zn alloy with a Zn-rich interlayer. The resulting alloy had a high Zn utilization ratio with uniform Zn plating/stripping reactions51. DES-Zn//AC capacitors showed 70.9% capacitance retention after 7000
Another strategy to alleviate Zn dendrite growth and H2evolution relies on utilizing nonaqueous electrolytes consisting of Zn salts and organic solvents. To date, most studies on Zn plating/stripping or Zn2+ion (de)intercalation for rechargeable ZBs have been performed in aqueous electrolytes, while ...

Three-dimensional Zn3V2O7(OH)2·2H2O microspheres have been successfully synthesized by a simple and facile liquid phase precipitation method without u
1 Materials The raw materials used for the preparation of NiAl2O4, CuAl2O4, and ZnAl2O4 aluminate spinels include Ni(NO3)2∙6H2O (nickel nitrate hexahydrate), Cu(NO3)2∙ 3H2O (copper nitrate trihydrate), Zn(NO3)2∙6H2O (zinc nitrate hexahydrate), Al(NO3)3∙9H2O (aluminum ...
In a typical synthesis, 0.290 g of iron chloride hexahydrate (FeCl3·6H2O), 0.16 g of zinc acetate dihydrate (Zn(Ac)2·2H2O) and 0.600 g of urea ((NH2)2CO) were dissolved into the above-mentioned mixed solution. Then, the solution was sealed into a 40 mL Teflon-lined...
Li Lei3, Xia Xiang1 & Xiao-Tao Zu1 Three ZnAl2O4 samples were prepared via a modified polyacrylamide gel method using a citric acid solution with different aluminum salt starting materials, including AlCl3∙6H2O, Al2(SO4)3∙18H2O, and Al(NO3)3∙9H2O under identical conditions...
Methanol (AR), isopropanol (AR), potassium hydroxide (AR), hydrochloric acid (AR), and Zn(Ac)2·2H2O (AR) were purchased from Sinopharm Chemical Reagent Co., Ltd, China. Zn plate was purchased from Shanghai Maikelong Co., Ltd. Commercial Pt/C (20 wt%), Pt/C + RuO2 (30 wt%)...
ZnCl2 (12.8 mmol, Aldrich) and SnCl4 Á 5H2O (6.4 mmol, Aldrich) were dissolved in deionized water (160 ml) under vigorous magnetic stirring. N2H4 Á H2O (N2H4 molar ratio/Zn ¼ 4/1, 8/1, 24/1) was then added to the reaction solution. White precipitates formed immediately, ...
