Summary
DL-O-Methylserine (MeSer) additive enhances aqueous zinc-ion battery (AZIB) performance by optimizing zinc ion diffusion and desolvation. This leads to significantly improved cycling stability and rate capability in AZIBs.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Aqueous zinc-ion batteries (AZIBs) are a promising energy storage technology.
- Severe dendrite growth and sluggish kinetics limit AZIB cycle life and rate capability.
Purpose of the Study:
- To introduce DL-O-Methylserine (MeSer) as an additive to improve AZIB performance.
- To investigate the mechanism by which MeSer enhances zinc ion deposition and desolvation.
Main Methods:
- Experimental characterization of electrode surfaces and electrochemical performance.
- Computational modeling to understand MeSer-ion interactions and electric double layer (EDL) effects.
Main Results:
- MeSer additive optimizes Zn2+ diffusion and facilitates desolvation.
- MeSer- adsorption on electrode surfaces compresses the EDL, promoting uniform Zn2+ deposition.
- Zn||Zn symmetric cells with MeSer showed 2320 h stability at 5 mA cm-2 and endured 600 h at 20 mA cm-2.
- Zn||V2O5 full cells retained 86% capacity after 3500 cycles at 5 A g-1.
Conclusions:
- MeSer significantly enhances the cycling stability and rate capability of AZIBs.
- EDL regulation via MeSer is an effective strategy for improving AZIB performance.
- This work paves the way for developing high-performance and long-lasting AZIBs.

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.

1.1K
Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or...

The degradation of metals due to natural electrochemical processes is known as corrosion. Rust formation on iron, tarnishing of silver, and the blue-green patina that develops on copper are examples of corrosion. Corrosion involves the oxidation of metals. Sometimes it is protective, such as the oxidation of copper or aluminum, wherein a protective layer of metal oxide or its derivatives forms on the surface, protecting the underlying metal from further oxidation. In other cases, corrosion is...

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...
