Can graphene store heat

Can graphene be used in thermal management?

In this review, we briefly outline the state-of-the-art and new developments in the field of thermal properties of graphene. In addition, as an example of a practical application of graphene in thermal management, we will describe graphene-enhanced phase-change materials (PCMs).

Does graphene have thermal properties?

Graphene, as a representative of two-dimensional materials, has attracted extensive attention for its excellent thermal properties. Ever since it has been discovered, researches have been carried out and achievements have been made both theoretically and practically.

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.

How hot is graphene at room temperature?

Graphene has a very high Debye temperature, ΘD 2100 K, such that the specific heat at room temperature is only about one-third that of the classical Dulong–Petit limit (Figure 2).

Can graphene be used as a heat spreader?

Graphene-based materials of various thicknesses have been applied as heat spreader, with thermal conductivity of 3200 W m −1 K −1.

Why is graphene a good material?

Impurities in a graphene sheet increase the reactivity of the substance. Its thermal conductivity and mechanical strength result in the good in-plan characteristics of graphite (independently around 3000 W m −1 K −1 and 1060 GPa), and its breakdown quality is comparable to that of carbon nanotubes, for virtually the same kind of defects.
