Abstract: The unique two-dimensional spatial structure gives graphene excellent chemical and physical properties and huge specific surface area. These make graphene a very promising material for energy storage applications. This paper reviews recent progress in the use of graphene in chemical energy storage, including hydrogen storage, supercapacitor, lithium ion batteries, lithium-sulfur batteries and lithium-air batteries. Relationships between different preparation methods of graphene and their chemical/electrochemical properties are discussed. Graphene could form three dimensional conductive network to enhance the electrochemical properties of electrodes materials, but also provide a buffer for the volume change during charging-discharging processes to extend the life-span. Further improvements of electrochemical performance are able to be achieved by optimizing the microstructure of composite materials. Finally, key issues related to practical applications of graphene are briefly discussed.
