Abstract
Solid electrolyte interface (SEI) is a critical factor that influences battery performance. SEI layer is formed by the decomposition of organic and inorganic compounds after the first cycle. This study investigates SEI formation as a product of electrolyte decomposition by the presence of flouro‐o‐phenylenedimaleimaide (F‐MI) additive. The presence of fluorine on the maleimide‐based additive can increase storage capacity and reversible discharge capacity due to high electronegativity and high electron‐withdrawing group. The electrolyte containing 0.1 wt% of F‐MI‐based additive can trigger the formation of SEI, which could suppress the decomposition of remaining electrolyte. The reduction potential was 2.35 to 2.21 V vs Li/Li+ as examined by cyclic voltammetry (CV). The mesocarbon microbeads (MCMB) cell with F‐MI additive showed the lowest SEI resistance (Rsei) at 5898Â Ω as evaluated by the electrochemical …
