“…Although there is a rapid growth of portable and wearable electronics [1,2,3,4,5,6,7,8,9], a crucial challenge facing today is the development of lightweight, flexible, and highperforming energy storage devices [10,11,12,13]. Supercapacitors (SCs) showing inherent rapid charge/discharge characteristics alongside unlimited lifetime have been considered as promising energy storage devices to supply power for various electronic devices [14,15,16,17,18,19,20]. A recent development in wire-shaped SCs (WSSCs) shows great promise in portable and wearable electronics applications due to their less weight, tiny volume, and high flexibility [21,22,23,24].…”
