Abstract:The slow reaction kinetics of Li−O is currently the most pressing technical obstacle to the development of lithium‐oxygen batteries. The Li2O2′s growth/decomposition pathways dominate the battery performance and can be optimized by exploring efficient cathode catalysts. Herein, we prepare regular, polycrystalline, oxygen vacancy (VO)‐riched PrOx uniformly anchored on few‐layered graphene (FLG) nanosheets to boost the Li−O reactions. XRD, TGA, XPS, SEM, TEM, SEAD, and electrochemical test techniques are used to… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
