Metal-Hydroxide Organic Frameworks for Aqueous Nickel-Zinc Batteries

Nano Letters
Hydroxides exhibit a high theoretical capacity for energy storage by ion release and are often intercalated with anions to enhance the ion migration kinetics. In this study, a series of metal-hydroxide organic frameworks (MHOFs) are synthesized by intercalating aromatic organic linkers into hydroxides using I-M/Ni(OH)2 (where M = Co2+, Cu2+, Mg2+, Fe2+)

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.

Gradient Structured Separator Enables Stable Aqueous Zinc Metal Batteries

Nano Letters
Developing a functional separator is an important strategy to improve the electrochemical performance of the Zn anode by suppressing the Zn dendrite growth and parasitic side reactions, thus advancing the aqueous zinc-ion batteries. Herein, we experimentally realize functional separator with gradient-structure based on CeF3 nanoparticles functionalized

Improving Aqueous Zinc Ion Batteries with Alkali Metal Ions

ACS Applied Materials & Interfaces
Aqueous zinc (Zn) ion batteries have received broad attention recently. However, their practical application is limited by severe Zn dendrite growth and the hydrogen evolution reaction. In this study, three alkali metal ions (Li+, Na+, and K+) are added in ZnSO4 electrolytes, which are subjected to electrochemical measurements and molecular dynamics ...

Design Strategies toward High‐Utilization Zinc Anodes for Practical Zinc‐Metal Batteries

Chemistry – A European Journal
AbstractAqueous Zn‐metal batteries (AZMBs) hold a promise as the next‐generation energy storage devices due to their low cost and high specific energy. However, the actual energy density falls far below the requirements of commercial AZMBs due to the use of excessive Zn as anode and the associated issues including dendritic growth and side reactions ...

Microstructure studies of zinc electrodeposits in zinc metal batteries

Rechargeable zinc batteries offer a safe and inexpensive alternative to lithium-ion batteries. However, their efficiency and lifespan are limited by hydrogen evolution and rough zinc deposition during the charging process. Yet there is a lack of fundamental understanding regarding the development of rough zinc morphologies and their impacts on hydrogen

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.
