Method for Creation of Fine Sulfur Particles with Graphene Oxide for Lithium/Sulfur Cells
Journal of the Electrochemical Society
High capacity and long cycle life are both desirable features for practical secondary cells. In this study, we compare two different synthesis processes for preparing active materials for lithium/sulfur cells using polysulfide and graphene oxide (GO) showing high sulfur utilization and cycling stability. The key factor determining cell performance is the oxygen-containing functional groups on GO and the fine structures. This study shows the possibility of application of GO for enhanced capacity and cycling stability.doi:10.1149/2.0181814jes fatcat:42ie7j4fwfhahdhpcrrtccq5ue
