Enhanced Solid Electrolyte Interphase Layer in Li-Ion Batteries with Fluoroethylene Carbonate Additives Evidenced by Liquid-Phase Transmission Electron Microscopy

The solid electrolyte interphase (SEI) layer is essential for battery performance and safety due to its electron insulation and Li-ion conduction. However, issues such as ongoing electrolyte decomposition and Li dendrite growth often arise. The most common strategy for improving the SEI is using ele...
