How do you prepare flexible electrode materials?

There are two main methods for preparing flexible electrode materials. One is coating or depositing the active material on a flexible substrate, and the other is preparing flexible free-standing materials, such as flexible films and fibers. A brief timeline showing the history of the development of various planar FSCs.

Are flexible carbon materials a good choice for a supercapacitor?

In view of both compressibility and high conductivity, flexible carbon materials could have the obvious advantage. For example, Wang et al. introduced free-standing and hydrophilic nitrogen (N)-doped carbon foams as high-performance electrodes for compressible supercapacitors.

What materials are used in a flexible supercapacitor?

In the future, they will continue to develop continuously to meet the various needs of life at this stage (Table 1). Electrode material is a key factor that determines the performance of flexible supercapacitor. Common electromagnetic materials mainly include carbonary materials, metal compound materials, and conductive polymer materials.

Can flexible electrodes be used for supercapacitors?

This work shows impressive potential in fabricating high-performance flexible electrodes for supercapacitors.

Are supercapacitors flexible?

As people pay more and more attention to supercapacitors, they also put forward higher requirements for the performance of supercapacitors, to ensure high conductivity and also take into account the flexibility. The composite of graphene and carbon-based materials is a good flexible electrode material.

What substrates are used for a flexible supercapacitor electrode?

The substrates to coat the active materials for fabricating the flexible supercapacitor electrode are categorized into conductive substrates including flexible metal films, carbon-based substrate and non-conductive substrates such as conventional paper, textiles, fibers, bendable polymer films.
