Abstract:We believe that Na-ion battery is a possible next-generation alternative to Li-ion battery because sodium, the most Earth-abundant alkali, is providing comparable performance of insertion materials to lithium counterpart. To realize comparable energy storage to Li-ion, development of high capacity sodium insertion materials is of a key issue because of inevitable low-voltage operation of Na-ion. Since the demonstration of 3-volt Na-ion battery [1], our group has studied non-graphitizable carbon (hard carbon) a… 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.
