Are graphene-based electrode materials suitable for supercapacitors?

Graphene-based materials in different forms of 0D, 1D, 2D to 3D have proven to be excellent candidates of electrode materials in electrochemical energy storage systems, such as supercapacitors.

What are the limits of graphene in supercapacitors?

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.

Why are graphene-based supercapacitors more expensive?

Graphene-based supercapacitors are more expensive. Because graphene-based supercapacitors are a newer technology, their production has not yet reached economies of scale. Furthermore, due to more stringent quality requirements, graphene continues to be more expensive to produce than activated carbon.

What are graphene-based hybrid supercapacitors?

Recently, graphene-based hybrid supercapacitors capable of providing up to 42 Wh l −1 have been reported 62. The advantage of these hybrid supercapacitors is that they work with aqueous electrolytes and can be produced in air without the need for expensive ‘dry room’ assembly.
