제목 Preparation and electrochemical property of graphene/Co3O4 composite anode for lithium-sulfur battery by using reduction methods
초록 Graphene/Co3O4 composite electrodes were studied for an application of lithium-sulfur battery. For this synthesis, we use the technology of ultrasonication and microwave assisted reduction methods. And, we use ethylene glycol as a reducing agent. The morphology and microstructure of samples were identified by scanning electron microscopy(SEM), transition electron microscopy(TEM), and X-ray diffraction(XRD). Electrochemical property was evaluated by cyclic voltammetry(CV). As an anode material, graphene could provide large number of active sites for nucleation of Co3O4 and excellent electron transfer path. In this study, an optimized configuration of the prepared sample and their electrochemistry were investigated.
