摘要
Disclosed in the present disclosure is a preparation method of a graphene flower, mainly lying in spray-drying graphene oxide solution to obtain a graphene oxide flower and then performing reduction on the same to obtain a graphene flower. Also disclosed in the present disclosure is use of the graphene flower in a lithium sulfur battery. The present disclosure is easy to operate, low cost, and suitable for scaled production, can improve the rate capability of a lithium sulfur battery while ensuring the high energy ratio of the lithium sulfur battery, thus greatly improving the energy density thereof, and can be applied in the field of high energy storage material and devices.
