▎ 摘　　要

NOVELTY - Preparing graphene nanosheets by using graphite ball milling of waste lithium battery negative pole comprises soaking the waste lithium battery cathode powder in clean water for a period of time after filtering and collecting the filter residue, roasting and collecting residual waste graphite powder, mixing and ball milling the waste graphite powder and interlayer stripping agent powder, cleaning and filtering the product after ball milling and drying the obtained filter residue to obtain the final product. USE - The graphene nanosheets is useful for modifying silicone rubber (claimed). ADVANTAGE - The method: can recycle the waste graphite of waste lithium battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene nanosheets prepared by above mentioned method.
