How smart supercapacitors are developed?

Various smart supercapacitors have been developed by designing the electrodes and electrolytes of the supercapacitors as well as simplifying the device configurations. This review summarizes the development of smart supercapacitors with self-healing, shape memory, electrochromism, and photodetection.

What are smart fiber supercapacitors?

Most of the smart fiber supercapacitors are designed in this configuration, because it can be easily integrated with other fiber-shaped electronic devices, such as sensors or solar cells, to achieve multifunctional systems.

Are smart supercapacitors self-healing?

Recently, a variety of smart supercapacitors have been successfully designed and fabricated by developing novel functional component materials and device configurations. In this review, we will present the recent developments in smart supercapacitors with self-healing, shape memory, electrochromism, and photodetection functions (Figure 1 ).

Can dielectric materials be used in advanced pulsed capacitors?

In the fast development of the power electronics, dielectric materials with high energy-storage density, low loss, and good temperature stability are eagerly desired for the potential application in advanced pulsed capacitors.

Can supercapacitors be smart energy storage devices?

The achievement of smart supercapacitors usually depends on the design of their configurations. However, conventional supercapacitors are mainly designed in button cells or spiral-wound configuration, which are too bulky and heavy to serve as smart energy storage devices.

Are shape memory materials available in smart supercapacitors?

However, still there exist lack of available shape memory materials in smart supercapacitors and their responsiveness is also slow. In addition, the shape memory materials cannot contribute to the capacity, which will degrade the energy density of whole supercapacitor devices.
