Abstract

Abstract : Only when a fluoride coating synchronously possesses a fluoride suspension with an appropriate pH and a small metal cation ionic radius, can it provide strong interface protection for excellent cyclic stability of high-voltage NCM cathodes. Abstract : The effect of fluoride coatings, an effective approach to suppress HF corrosion, on the cycling stability of NCM523 cathodes is systematically studied. It is the first study to reveal that fluoride coatings significantly restrain interfacial reactions when, simultaneously, the fluoride suspension possesses an appropriate pH (near 4.0) and there is a small cation ionic radius.
