Abstract: Sodium (Na)-ion batteries (NIBs) are attracting noticeable interest in recent years as post lithium (Li)-ion batteries (LIBs) due to the "unlimited" abundance of sodium in the Earth`s crust. To improve the performance of secondary batteries, the solid electrolyte interface (SEI) film-forming additives into electrolyte solutions are widely used in general and fluoroethylene carbonate (FEC) additive is known to increase the NIB performance, while difluoroethylene carbonate (DFEC) is inefficient in spite of a si…
