A straightforward approach to improve NCM523/graphite pouch battery performance in a wide temperature range at 4.35 V using film-forming additive N-phenylimidodisulfuryl fluoride (PhFSI)

A novel film-forming additive N -phenylimidodisulfuryl fluoride (PhFSI), was delicately designed, synthesized and proved to excellently boost the electrochemical performance of NCM523/graphite batteries with 1 wt% in a wide temperature range from −10 to 45 °C at 4.35 V.
