摘要
An atomic layer deposited (ALD) Al2O3 coating applied to sulfur cathodes has been studied in this paper. It is demonstrated that the Al2O3 coating improves the cycling stability of Li-sulfur batteries. The underlying mechanism by synchrotron-based X-ray photoelectron spectroscopy was investigated. The coating layer not only protects the polysulfide from dissolution, but also facilitates the utilization of sulfur, demonstrating improved electrochemical performances.
