Title: GRAPHENE FLOWER PREPARATION METHOD AND APPLICATION OF SAME IN LITHIUM SULPHUR BATTERY
Abstract:
Disclosed in the present invention is a graphene flower preparation method, mainly comprising spray-drying graphene oxide solution to obtain a graphene oxide flower; and then reducing same to obtain a graphene flower. Also disclosed in the present invention is an application of said graphene flower in a lithium sulphur battery. The present invention is easy to operate, low cost, and suitable for scaled production, can improve the rate capability of a lithium sulphur battery whilst ensuring the high energy ratio of the lithium sulphur battery, thus greatly improving the energy density thereof, and can be used in the field of high energy storage material and devices.
