Addressing interfacial challenges in lithium metal batteries: A multi-pronged approach with 2-FBSA

Caption

This study explores the effectiveness of 2-fluorobenzenesulfonamide (2-FBSA) as a multifunctional additive in lithium metal batteries. 2-FBSA modifies the electrolyte solvation structure, lowers the Li+ desolvation energy barrier, and promotes faster Li+ transport. Its decomposition forms a robust solid electrolyte interphase (SEI) layer rich in inorganic Li salts, effectively suppressing Li dendrites and mitigating parasitic reactions. This leads to significantly improved cycling stability and rate performance in both Li-Li symmetric cells and Li-LiFePO4 full cells, offering a promising solution for the practical application of lithium metal batteries.
