Understanding the Interplay between Artificial SEI and Electrolyte Additives in Enhancing Silicon Electrode Performance for Li-Ion Batteries

Maintaining a stable solid electrolyte interphase (SEI) is crucial for Li-ion battery safety, especially with high-capacity anode containing silicon. Therefore, our study explored long-term cycling of Si electrodes with artificial alucone-based SEI, deposited by molecular layer deposition (MLD) in combination with a fluoroethylene carbonate (FEC) electrolyte additive. MLD of flexible Li-ion permeable artificial SEI coatings onto electrode resulted in improved capacity, enhanced Si electrode cycle life and capacity retention.
