Abstract

Solid Electrolyte Interphase (SEI) can prolong battery life but has issues with stability and electrochemical performance, which can be overcome by additives. Electrolyte additives can stabilize SEI and Cathode Electrolyte Interphase (CEI) layers, prevent dendrite formations, increase capacity retention, and enhance the cycling performance of batteries. Drawbacks such as lithium plating should be addressed before the development of electrolyte additives for commercial use. The functional synthetic additives developed through retrosynthesis may create a thermodynamically stable interphase and add spatial versatility. Rigorous theoretical calculations in conjunction with cutting-edge experimental methodology and SEI film characterization are necessary to comprehend the proper reaction route.
