Other featured supercapacitors with excellent flexibility, miniature and integrated functions are also reviewed. Recent development of supercapacitor based on laser scribed graphene are discussed demonstrating that laser scribing technology can simply induce graphene and simultaneously pattern graphene electrodes for supercapacitors.
