A highly stable pre-lithiated SiOx anode coated with a “salt-in-polymer” layer

Abstract

An artificial “salt-in-polymer” SEI, composed of poly-(1,3-dioxolane) and high-modulus fluorinated products generated from the in situ decomposition of Li salts, was constructed on the surface of Li-MSiOx particles. This LiF-rich SEI helps to maintain the structural integrity of Li-MSiOx particles and improves the Li storage reversibility of the Li-MSiOx anode.
