Summary
Researchers developed a novel artificial solid electrolyte interphase (ASEI) to protect lithium-tin (Li-Sn) alloy anodes in lithium metal batteries. This ASEI prevents dendrite formation, enhancing battery stability and performance.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Lithium metal secondary batteries offer high energy density but suffer from dendrite formation and electrolyte reactions at the anode.
- Lithium-tin (Li-Sn) alloys are promising anode substrates but require protection against degradation.
Purpose of the Study:
- To develop a protective layer for Li-Sn alloy anodes to enhance the stability and cycle life of lithium metal batteries.
- To investigate the efficacy of an artificial solid electrolyte interphase (ASEI) in preventing lithium dendrite growth and side reactions.
Main Methods:
- Fabrication of an ASEI layer via electrochemical oxidation and polymerization of 1,3-dioxolane with LiTFSI additive.
- Electrochemical testing of Li-Sn alloy anodes with ASEI for lithium deposition/stripping.
- Evaluation of Li-Sn alloy anodes protected by ASEI in lithium-sulfur full cells.
Main Results:
- The ASEI layer is flexible, stable, ion-conductive, and electrically insulating.
- ASEI-protected Li-Sn anodes demonstrated stable cycling with 98.4% average Coulombic efficiency at 1 mA cm⁻².
- Li-Sn anodes remained uniform and smooth, free from dendrites and cracks after cycling.
- Lithium-sulfur full cells utilizing ASEI-protected anodes showed improved discharge capacity and cycleability.
Conclusions:
- The developed ASEI strategy effectively suppresses lithium dendrites and electrolyte reactions on Li-Sn alloy anodes.
- This facile ASEI formation method offers a promising solution for stable and high-performance lithium metal batteries.

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

212.1K
The cell cycle occurs over approximately 24 hours (in a typical human cell) and in two distinct stages: interphase, which includes three phases of the cell cycle (G1, S, and G2), and mitosis (M). During interphase, which takes up about 95 percent of the duration of the eukaryotic cell cycle, cells grow and replicate their DNA in preparation for mitosis.

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).

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...

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.
