▎ 摘　　要

NOVELTY - Preparing a modified membrane comprises mixing zeolitic imidazolate framework-67 (ZIF-67) doped reduced graphene oxide (rGO) (ZIF-67@rGO) and binder polyvinylidene fluoride (PVDF) according to 9:(0-3) to obtain a coating slurry. The coating slurry is uniformly coated on the surface of the separator (Celgard2400 separator), and then dried in a vacuum to obtain the ZIF-67@rGO modified separator. USE - Method for preparing a modified membrane for lithium-sulfur batteries. ADVANTAGE - The modified membrane shows excellent cycle performance and multiplying power performance when it is used for a sulfur lithium battery. The method is simple, cost-effective, environment-friendly, and has good industrial application prospect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a MOF@rGO modified membrane for lithium-sulfur batteries, which is prepared according to the method; and (2) a method for using the MOF@rGO modified membrane, which involves using modified membrane for lithium-sulfur batteries.
