Graphene has now enabled the development of faster and more powerful batteries and supercapacitors. In this Review, we discuss the current status of graphene in energy storage, highlight ongoing research activities and present some solutions for existing challenges.
This will allow the design of novel materials and composites with custom properties and could enable the practical use of graphene-based materials in energy-storage devices. Another issue to be considered in graphene composites is the accessibility of the active materials to the electrolyte.
Few-layered graphene may have an important role in the progress of other battery chemistries. For example, an aluminium-ion battery was recently reported that can be fully charged in under one minute because of the ultrafast ion intercalation into 3D graphene foams 52. Ultrathin current collectors for lightweight devices.
Thus, supercapacitors based on graphene could, in principle, achieve an EDL capacitance as high as ∼ 550 F g −1 if the entire surface area can be fully utilized. However, to understand the limits of graphene in supercapacitors, it is important to know the energy density of a fully packaged cell and not just the capacitance of the active material.
The fundamental properties of graphene make it promising for a multitude of applications. In particular, graphene has attracted great interest for supercapacitors because of its extraordinarily high surface area of up to 2,630 m 2 g −1.
This review highlights recent developments in 3D porous graphene networks (3DPGNs) for energy-storage applications. The synthetic methods for the preparation of 3DPGNs and their hybrids are introduced, and their utilizations in lithium-ion batteries and supercapacitors are summarized along with the pros and cons.
