Graphene-Vanadium Oxide Nanowire, Method for Preparation Thereof, Positive Active Material Comprising the Same and Lithium Battery Comprising the Positive Active Material

摘要

The present disclosure is directed to a graphene-vanadium oxide nanowire including a nanowire core including vanadium oxide and a shell formed on the surface of the nanowire core and including graphene oxide. The graphene-vanadium oxide nanowire having improved capacity stability can be provided by using the graphene-vanadium oxide nanowire according to the present disclosure, the method for preparing the same, and a positive active material and a secondary battery including the same. In addition, by using the graphene-vanadium oxide nanowire according to the present disclosure as a positive active material, it is possible to provide a secondary battery having improved cycle characteristics and capacity retention rates.
