Summary
Lithium metal batteries offer higher energy density but face safety challenges. This review covers lithium metal anode issues and interfacial engineering for safer, commercialized batteries.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Lithium metal batteries (LMBs) offer significantly higher energy density compared to lithium-ion batteries (LIBs), making them attractive for electric transportation.
- The primary obstacle to LMB commercialization is the poor safety and performance associated with lithium metal (Li) anodes.
- Understanding the fundamental mechanisms and developing effective solutions are crucial for advancing LMB technology.
Purpose of the Study:
- To provide a comprehensive review of the challenges, characterization techniques, and interfacial engineering strategies for lithium metal anodes.
- To consolidate current knowledge on Li anode issues in both liquid and solid-state LMBs.
- To identify research gaps and stimulate new solutions for the commercialization of LMBs.
Main Methods:
- Literature review of theoretical and experimental studies on Li anodes.
- Analysis of characterization methods for evaluating Li anode performance and safety.
- Synthesis of information on interfacial engineering approaches for liquid and solid LMBs.
Main Results:
- Identification of key challenges including dendrite formation, low Coulombic efficiency, and safety hazards.
- Overview of advanced characterization techniques for in-situ and ex-situ analysis of Li anodes.
- Summary of interfacial engineering strategies, such as solid electrolytes and protective layers, to mitigate Li anode issues.
Conclusions:
- Addressing the challenges of Li anodes through comprehensive understanding and targeted interfacial engineering is essential for LMB commercialization.
- Further research is needed to develop robust and scalable solutions for safe and high-performance LMBs.
- This review aims to guide future research towards accelerating the adoption of LMBs in transportation electrification.

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...

01:19Acid Halides to Alcohols: LiAlH4 Reduction
2.8K
Acid halides are reduced to alcohols in the presence of a strong reducing agent like lithium aluminum hydride.
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...

633
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.

01:20Amides to Amines: LiAlH4 Reduction
4.7K
Amide reduction with strong reducing agents like lithium aluminum hydride proceeds through a nucleophilic acyl substitution to form amines. Primary, secondary, and tertiary amides yield primary, secondary, and tertiary amines, respectively.
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.

26.3K
In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...

20.8K
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
