Summary
This study introduces a fluorine-free diluent strategy for advanced batteries, significantly reducing lithium metal corrosion and enhancing battery lifespan for practical energy storage applications.
Area of Science:
- Electrochemistry
- Materials Science
- Energy Storage
Background:
- Localized high-concentration electrolytes (LHCEs) offer improved cycling stability but suffer from spontaneous corrosion due to fluorinated diluents reacting with lithium metal.
- Developing stable and high-performance electrolytes is critical for advancing battery technology and next-generation energy storage.
- Lithium metal batteries require electrolytes that prevent dendrite formation and ensure long-term stability.
Purpose of the Study:
- To develop a fluorine-free, corrosion-resistant diluent (CRD) strategy for advanced battery electrolytes.
- To investigate the impact of a benzene-based CRD and butyl methyl ether solvent on electrolyte performance and lithium metal stability.
- To demonstrate enhanced cycle and calendar life in batteries utilizing the novel electrolyte system.
Main Methods:
- Formulation of a novel electrolyte using benzene as a corrosion-resistant diluent (CRD) and butyl methyl ether as the primary solvent.
- Electrochemical testing to evaluate cycling stability, cycle life, and calendar life of the CRD-based electrolyte.
- Analysis of electrode-electrolyte interfaces to understand the mechanism of corrosion suppression and solvation structure.
Main Results:
- The CRD-based electrolyte demonstrated superior durability and stability compared to conventional LHCEs.
- The fluorine-free electrolyte effectively suppressed lithium metal corrosion by promoting an anion-dominated solvation structure.
- Significant extensions in both cycle life and calendar life were achieved with the novel electrolyte design.
Conclusions:
- The CRD strategy offers a promising approach for creating stable, fluorine-free electrolytes for advanced batteries.
- This electrolyte design enhances electrode-electrolyte interface stability, crucial for high-performance energy storage.
- The cost-effective and robust system presents significant advantages for the practical application of next-generation batteries.

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...

Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Substances that undergo either a physical or a chemical change in solution to yield ions that can conduct electricity are called electrolytes. If a substance yields ions in solution, that is, if the compound undergoes 100% dissociation, then the substance is a strong electrolyte. Complete dissociation is indicated by a single forward arrow. For example, water-soluble ionic compounds like sodium chloride dissociate into sodium cations and chloride anions in aqueous solution.

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).
