Nov 1, 2024 · Flexible Micro-supercapacitors (FMSCs) are revolutionizing smart wearable and implantable devices with their high energy density, superior power density, and exceptional
Capacitance plays an important role as an indispensable energy storage system in the microgrid. As a new type of energy storage device, supercapacitor has become one of the preferred devices for microgrid energy storage with its irreplaceable superiority. The microgrid consists of micro power supplies, loads, energy storage, and energy managers.
The supercapacitor energy storage system can effectively solve this problem. It can store the excess power of the power supply when the load is low, and feed back to the micro grid to adjust the power demand when the load is high.
Accordingly, smart supercapacitors have been widely focused on and studied by researchers recently with the introduction of intelligent functions, such as electrochromism, self-healing, and shape memory, into supercapacitors to broaden their application fields and promote their smart development.
Because supercapacitors can quickly absorb and release high-power electric energy, it is very suitable to be applied to the power quality adjustment device of the micro-grid to solve some transient problems in the system, such as instantaneous power failure and voltage swell caused by system failure. Problems such as voltage dips, etc.
At present, these new energies mainly include batteries 13 - 15 and supercapacitors. 16 - 18 Because of their high power density, supercapacitors can effectively meet people's pursuit of a fast-paced life, and more researchers will pay attention to them.
A self-charging supercapacitor 42 is connected with other external media, such as piezoelectric nanogenerator, 48 friction nanogenerator, 49 and solar cell, 50 and converts mechanical energy and solar energy (SE) into electrical energy for storage to realize the self-charging of the supercapacitor.
