Graphene For Batteries, Supercapacitors And Other Energy Storage - Batteries Featured Graphene Graphene Production
Synthesis and assembly of . Graphene sheets can be manipulated to form macroscopic structures that take advantage of the unique features of the individual graphene sheets to enable the construction of new graphene architectures that are useful for many different applications. 2D graphene sheets can be assembled into macroscopic structures of all dimensionalities: 0D dots, 1D linear structures, 2D , 3D monoliths and potentially 4D self-folding structures. Methods for the preparation of these structures and how they affect the properties and applications of graphene are described.

Graphene currently is the most studied material on the planet – this is especially true for charge storage and the results from many laboratories confirm its potential to change today’s energy-storage landscape.

Specifically, graphene could present several new features for energy-storage devices, such as smaller capacitors, completely flexible and even rollable energy-storage devices, transparent , and high-capacity and fast-charging devices.

These and other features are explored in detail in a review article in Nature Reviews Materials (“Graphene for batteries, supercapacitors and beyond”).

Despite notable progress, the future of graphene in the energy-storage market is uncertain because of several challenges. The authors discuss and propose solutions to these challenges and also briefly discuss the potential of other emerging 2D materials for energy-storage applications.
