Summary of graphene energy storage

Can graphene be used in energy storage/generation devices?

We present a review of the current literature concerning the electrochemical application of graphene in energy storage/generation devices, starting with its use as a super-capacitor through to applications in batteries and fuel cells, depicting graphene's utilisation in this technologically important field.

Are graphene films a viable energy storage device?

Graphene films are particularly promising in electrochemical energy-storage devices that already use film electrodes. Graphene batteries and supercapacitors can become viable if graphene films can equal or surpass current carbon electrodes in terms of cost, ease of processing and performance.

Can graphene lead to progress in electrochemical energy-storage devices?

Among the many affected areas of materials science, this 'graphene fever' has influenced particularly the world of electrochemical energy-storage devices. Despite widespread enthusiasm, it is not yet clear whether graphene could really lead to progress in the field.

Can graphene be used as a Li-ion storage device?

In light of the literature discussed above current research regarding graphene as a Li-ion storage device indicates it to be beneficial over graphite based electrodes, exhibiting improved cyclic performances and higher capacitance for applications within Li-ion batteries.

Is graphene a good electrode for energy storage?

Both strategies have achieved notable improvements in energy density while preserving power density. Graphene is a promising carbon material for use as an electrode in electrochemical energy storage devices due to its stable physical structure, large specific surface area (~ 2600 m 2 ·g –1), and excellent electrical conductivity 5.

Can graphene-based composites be used for energy storage?

While graphene-based composites demonstrate great potential for energy–storage devices, several challenges need to be addressed before their practical application in various fields.
