Can graphene be used in energy storage devices?

Graphene is capable of enhancing the performance, functionality as well as durability of many applications, but the commercialization of graphene still requires more research activity being conducted. This investigation explored the application of graphene in energy storage device, absorbers and electrochemical sensors.

Why is graphene a good material?

The graphene regarding its crystals at the microscopic stage are usually preserved and very stable . These characteristics of graphene contributes to their good conduction of heat. In terms of mechanical characteristics, they are considered as a material with high strength.

Why is graphene used in composites?

Graphene are used as functional materials in composites and this tend to improve the characteristics as well as the performance of the composite. Graphene having good elasticity, strength and porosity have positive effect on the composites when combined together. The strength of some graphene increases under compression [, , ].

How is graphene synthesized on a large scale?

Progress in chemical exfolation of graphite. Another approached used to synthesize graphene on large scale is electrochemical reduction [, , ]. The monolayer flakes reduced graphene oxide was produced in 1962. Hydrazine reducing agent can be used in the elimination of oxygen groups.

Which 3D graphene structure is used for supercapacitor applications?

3D graphene structure such as graphene foams, sponges, and aerogels was also investigated for supercapacitor applications due to their unique structure containing micro- meso- and macro-interconnected pores, high surface area, and fast ion/electron transport channels.

How can graphene improve DSSC performance?

A composite of graphene with polymer such as blends of polyvinylidene fluoride (PVDF), polyethylene oxide (PEO, and hexafluoro propylene (HEP), was found to be effective method for improving the performance of DSSC as shown in Fig. 13.
