3-(Phenylsulfonyl)propionitrile as a higher voltage bifunctional electrolyte additive to improve the performance of lithium-ion batteries

Abstract

The effects of 3-(phenylsulfonyl)propionitrile (PSPN) as a higher voltage bifunctional additive in the electrolyte on the formation of a solid electrolyte interface (SEI) on both LiCoO₂ cathodes and graphite anodes are investigated using the half-cell method.
