Abstract: (602 Views)
The output power of energy storage including supercapacitors and batteries strongly depends on the type of material and the structural quality of the materials used to make their electrodes. The two main problems that lead to the structural deterioration of the electrodes' materials and finaly lead to the decrease in the energy density of the storage device are: a) particle pulverization and collapse of the electrode structure and b) the volume expansion. On the other hand, some of these electrodes show poor electrical properties. In the recent decade, the use of graphene derivatives in the manufacture of electrodes for supercapacitors and lithium-ion batteries with the aim of increasing the conductivity of electrodes and reducing the negative effects of their damage has been the focus of research teams. In this study, the achievements of the aforementioned researches have been reviewed and tried to be presented in a way that can be used by academic and industrial researchers. Investigations showed that among graphene derivatives, reduced graphene oxide has received the most attention in this application due to its high electrical conductivity, higher specific surface area, high reactivity and chemical stability. It is noteworthy that the higher electrical conductivity of rGO compared to GO due to the higher C/O ratio in rGO compared to GO. The focus in this article is on investigating the specific capacity of composites containing rGO for energy storage devices. The result of this study showed that the use of this type of improved composites using rGO has increased the specific capacity and improved the stability of the electrodes.
Keywords: Energy storage devices, Supercapacitors Lithium-ion batteries, reduced graphene oxide(rGO), Specific capacity.
