Overlooked calendar issues of aqueous zinc metal batteries

Joule
Although the zinc metal plating and stripping chemistry offers a high specific capacity, this process suffers from poor reversibility, a crucial factor for long-term energy storage. Most studies so far have been focusing on cyclic aging but overlooked the impact of calendar aging on zinc metal behavior.

Interfacial ionic effects in aqueous zinc metal batteries

Energy Storage Materials
Zn metals anodes (ZMAs) are most attractive for emerging aqueous zinc metal batteries (AZMBs). However, the practical application of AZMBs is still impeded by various formidable issues like uncontrolled Zn dendritic growth, hydrogen evolution reaction, and severe corrosion of ZMAs.

Organic Cations Texture Zinc Metal Anodes for Deep Cycling Aqueous Zinc Batteries

Advanced Materials
AbstractManipulating the crystallographic orientation of zinc (Zn) metal to expose more (002) planes is promising to stabilize Zn anodes in aqueous electrolytes. However, there remain challenges involving the non‐epitaxial electrodeposition of highly (002) textured Zn metal and the maintenance of (002) texture under deep cycling conditions.

Bifunctional gel coating for stabilizing zinc metal anodes in aqueous zinc-ion batteries

Journal of Colloid and Interface Science
Currently, the zinc anode faces significant challenges such as dendrite growth, corrosion, and hydrogen evolution, which severely limit the practical applications of aqueous zinc-ion batteries. To address these issues, this study designed a zinc anode (denoted as CG@Zn) coated with a gel composed of carboxymethyl cellulose sodium (CMC) and glucose ...

Electrolyte Engineering for Aqueous Zinc Metal Batteries

Zn symmetric cell can run for more than 3000 h under the current density of 2 mA cm-2. When zinc anodes were coupled with an activated carbon cathode with a mass loading of 8 mg cm-2, the powering device showed high reversibility. Although additives can enhance the performance of zinc metal anodes, their low concentration limits their ability to ...
