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-MSiO x particles. This LiF-rich SEI helps to maintain the structural integrity of Li-MSiO x particles and improves the Li storage reversibility of the Li-MSiO x anode.
