Nanomaterials electrochemical energy storage

Why are nanomaterials important for electrochemical energy storage?

Nanomaterials have attracted considerable attention for electrochemical energy storage due to their high specific surface area and desirable physicochemical, electrical, and mechanical properties.

Which nanomaterials are used in energy storage?

Although the number of studies of various phenomena related to the performance of nanomaterials in energy storage is increasing year by year, only a few of them—such as graphene sheets, carbon nanotubes (CNTs), carbon black, and silicon nanoparticles—are currently used in commercial devices, primarily as additives (18).

Can nanomaterials improve the performance of energy storage devices?

The development of nanomaterials and their related processing into electrodes and devices can improve the performance and/or development of the existing energy storage systems. We provide a perspective on recent progress in the application of nanomaterials in energy storage devices, such as supercapacitors and batteries.

What are the limitations of nanomaterials in energy storage devices?

The limitations of nanomaterials in energy storage devices are related to their high surface area—which causes parasitic reactions with the electrolyte, especially during the first cycle, known as the first cycle irreversibility—as well as their agglomeration.

Are nanostructured materials a suitable electrode material for energy storage devices?

Nanostructured materials have become established as capable electrode materials for these energy storage devices. Compared with bulk materials, nanostructured materials provide a high specific electroactive surface area that can enhance charge and energy storage capacity.

Can nanomaterials be used for energy systems?

Recent developments in the syntheses of nanomaterials with controlled structures would speed up the application of various kinds of electrode materials for energy systems. Further development in this exciting field will surely revolutionize the way in which future energy techniques are developed.
