Abstract

Abstract : An artificial "salt-in-polymer" SEI was constructed on the surface of Li-MSiO x particles to maintain the structural integrity and inhibit the parasitic reaction at the electrode/electrolyte interface during cycling. 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-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.
