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