Zinc metal as anodes has been widely used for electrochemical energy storage devices using aqueous electrolytes, due to its cost effective, eco-friendliness, as well as low redox potential in aqueous solutions. However, Zn prefers to grow into plate-like structures that vertically stand on current...
Metallic zinc (Zn) has been regarded as an ideal anode material for aqueous batteries because of its high theoretical capacity (820 mA h g–1), low potential (−0.762 V versus the standard hydrogen electrode), high abundance, low toxicity a
In addition, the annual capacity extended from 55,000 tons to 74,000 tons during several expansion stages.Main products are zinc alloys for hot galvanizing and zinc anodes for plating.This paper describes these recent improvements and operations. 展开 关键词:...

This study opens an avenue for the highly efficient utilization of zinc metal electrodes for advanced energy storage applications while the fundamental knowledge gained can also be applied to other metal anodes. 展开 年份: 2017 收藏 引用 批量引用 报错 分享 ...
Stable plating/stripping of metal electrodes under high power and high capacity remains a great challenge. Tailoring the deposition behavior on the substrate could partly resolve dendrites’ formation, but it usually works only under low current densitie
Here we show a backside-plating configuration that enables long-term cycling of zinc metal batteries without shorting. We demonstrate 800 stable cycles of nickel–zinc batteries with good power rate (20 mA cm−2, 20 C rate for our anodes). Such a backside-plating method can be applied...
It is used to form a wide variety of alloys including brass, bronze, various solders, and nickel silver, in galvanizing iron and other metals, for electric fuses, anodes, meter cases and batteries, and in roofing, gutters, and various household objects. US pennies minted after 1982 consist ...
with Zn or intercalation-type anodes. As cathodes, carbons can store charges via the electric double-layer capacitance. For the electric double-layer capacitance, the charges can be stored electrostatically on the surface between electrode and electrolyte through a non-Faradic process, where the ...
The surface chemistry of solid electrolyte interphase is one of the critical factors that govern the cycling life of rechargeable batteries. However, this chemistry is less explored for zinc anodes, owing to their relatively high redox potential and limited choices in electrolyte. Here, we report th...
