Graphene energy storage prospects

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 composites suitable for energy storage applications?

As capacity requirements in energy storage applications increase, graphene composites such as the embedment/encapsulation of nanostructured materials in graphene have been developed to meet these requirements.

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.

Are graphene based nanocomposites a good choice for energy storage & conversion?

The high electrochemical performance with the high-power density, long lifetime and excellent charge-discharge capacity proves that both MXene and graphene-based nanocomposites are highly efficient for energy storage and conversion applications. Graphene boasts outstanding thermal, mechanical, and electrical attributes.

Can graphene reduce reliance on traditional energy resources?

Here, graphene and its derivatives are promising in advanced industrial applications and in reducing reliance on traditional energy resources due to hexagonally arranged single sp 2 carbon atom layers, high intrinsic carrier mobility, ultrahigh specific surface areas, high optical transmittances, and exceptional mechanical properties (Fig. 1).

Can graphene hybridization be used for energy storage?

Finally, future prospects and directions on the exploration of graphene hybridization toward the design and construction of viable, high-class, and even newly-featured ( e.g., flexible) energy storage materials, electrodes, and systems will be presented.
