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.
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.
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.
Smart-hybrid supercapacitors are found to have potential in developing superior energy devices (with increased specific capacitance, energy-storing capability, and high durability). Currently, electronic devices are inevitable in the digital world to be employed for multitasking toward betterment of life.
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 ).
In addition, wire-shaped supercapacitors based on shape memory materials have received considerable interest in the next generation of portable and wearable electronic devices. However, the bottleneck in this field is how to develop devices with excellent electrochemical performance while maintaining good recoverability and flexibility.

Supercapacitors vs. Batteries: What''s the Difference?
The big difference is that capacitors store power as an electrostatic field, while batteries use a chemical reaction to store and later release power.
