Recent progress in constructing halogenated interfaces for highly stable lithium metal anodes

Yaoda Wang et al.

Summary: Lithium metal batteries (LMBs) have great potential for enhancing energy density, but the uncontrolled dendrite growth and formation of solid electrolyte interface (SEI) limit their practical applications. Constructing halogenated interfaces on Li metal anodes (LMAs) can solve these challenges by passivating active Li surfaces, regulating Li ion diffusion and migration, and improving interface mechanical stability. This review discusses the effects of various halogenated interfaces on LMAs and summarizes the strategies and protection mechanisms for constructing advanced halogenated interfaces.

Nonafluorobutane-1-Sulfonic Acid Induced Local High Concentration Additive Interface for Robust SEI Formation of High-Voltage (5 V-Class) Lithium Metal Batteries

Jinqiu Zhou et al.

Summary: In order to optimize the degradation issues in high-voltage lithium metal batteries, it is necessary to have robust solid-electrolyte interfaces (SEI) on both the anode and cathode surfaces. The introduction of a nonafluorobutane-1-sulfonic acid (NFSA) additive assists in the formation of a stable and robust SEI to protect both electrodes. By using NFSA, high concentrations of NFSALi and NFSA(-) can be achieved on the surface of the anode and cathode respectively, resulting in the formation of conformal and dense SEI passivation films, ensuring stable operation of the battery.

Highly Soluble Lithium Nitrate-Containing Additive for Carbonate-Based Electrolyte in Lithium Metal Batteries

Venkata A. K. Adiraju et al.

Summary: While the poor solubility of lithium nitrate (LiNO3) limits its use in conventional carbonate-based electrolytes, a new LiNO3-containing electrolyte additive called 1-trimethylsilyl imidazole lithium nitrate adduct (TMSILN) has been synthesized to improve its solubility. The presence of TMSILN in the electrolyte significantly enhances the electrochemical performance of Li/Li and NCM622/Li cells, resulting in a circular morphology of deposited lithium metal with a thin surface film containing lithium nitrate decomposition products. This improvement is attributed to the favorable features of the SEI and morphology of the deposited lithium with TMSILN additive.
