  • Synthesis method for cathode material in lithium-sulfur battery
    Patent number: 10147941
    Abstract: The present invention relates to a method for synthesizing graphene/sulfur composite, involving the steps of mixing graphene oxide (GO) with a hydrogen sulfide (H2S)-releasing agent in a sealed vessel, causing the H2S-releasing agent to release hydrogen sulfide, and then allowing the hydrogen sulfide to react with the graphene oxide at an elevated temperature and pressure to form said graphene/sulfur composite.
    Type: Grant
    Filed: March 15, 2016
    Date of Patent: December 4, 2018
    Assignee: THE HONG KONG POLYTECHNIC UNIVERSITY
    Inventors: Linfeng Fei, Yu Wang
