Ultrathin oxide coatings are demonstrated to offer multiple functions for improving the cycling performance of lithium ion batteries. The coatings can serve as an artificial solid electrolyte interphase layer, which significantly suppresses electrolyte decomposition as well as mitigates mechanical degradation. Structure modification is critical for increasing the ion conductivity, and therefore leads to improved current efficiency.
