rGO/nano Sb composite: a high performance anode material for Na+ ion batteries and evidence for the formation of nanoribbons from the nano rGO sheet during galvanostatic cycling

摘要: Lithium ion batteries exhibit high energy and power densities, thereby making them a promising sources for multifarious applications. However, the abundance of lithium (Li) is one major critical issues using Li battery technologies. Therefore, large-scale applications sodium (Na) apt alternatives portable electronics instead expensive batteries. One challenging in Na+ difficulty to understand chemistry involved view large size as compared Li+ ion, which makes alloying/dealloying difficult during cycling. Hence, this present work, we explore an innovative concept storing ions reduced graphene oxide/antimony (Sb) metal composites. Such rGO/Sb composite simplest ways enhance electrochemical performance metal-based anodes Furthermore, it seen that nano rGO sheet transforms nanoribbons upon galvanostatic cycling, evidenced by TEM.
