Cyclic voltammograms indicate the cells with additive form good solid-electrolyte interphases (SEIs) during the first cycle, whereas no additive cell needs more cycles to form a functional SEI. X-ray photoelectron spectroscopy reveals LiBMFMB could reduce the decomposition of LiPF6 salt and solvents, resulting in thinner SEI.
