Cover Story: Wan ZF, Chen X, Gu M. Laser scribed graphene for supercapacitors. Opto-Electron Adv 4, 200079 (2021).
Supercapacitors, with the merits of both capacitors for safe and fast charge and batteries for high energy storage have drawn tremendous attention. Recently, laser scribed graphene has been increasingly studied for supercapacitor applications due to its unique properties, such as flexible fabrication, large surface area and high electrical conductivity. The laser scribing technology can simply induce graphene and simultaneously pattern the graphene electrodes for supercapacitors.
The research group of Prof. Min Gu from Centre for Artificial-Intelligence Nanophotonics (CAIN) of University of Shanghai for Science and Technology introduced the recent development of supercapacitor based on laser scribed graphene. In this review, this laser scribed graphene was applied for electrochemical double-layer capacitors, pseudo-capacitors and hybrid supercapacitors. Featured supercapacitors with excellent flexible, miniatured and integrated functions were also reviewed. In the end, the advanced technologies, such as artificial intelligence and radiative cooling were proposed to further improve the performance of supercapacitors in this research field.
