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).
These applications and the need to store energy harvested by triboelectric and piezoelectric generators (e.g., from muscle movements), as well as solar panels, wind power generators, heat sources, and moving machinery, call for considerable improvement and diversification of energy storage technology.
Smart energy storage devices, which can deliver extra functions under external stimuli beyond energy storage, enable a wide range of applications. In particular, electrochromic (130), photoresponsive (131), self-healing (132), thermally responsive supercapacitors and batteries have been demonstrated.
There is enormous interest in the use of graphene-based materials for energy storage. Graphene-based materials have great potential for application in supercapacitors owing to their unique two-dimensional structure and inherent physical properties, such as excellent electrical conductivity and large specific surface area.
The energy storage capacity of CNTs is augmented through structural modifications, including the introduction of defect sites and edge functionalization.
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.
