Low cost and flexible mesh-based supercapacitors for promising large-area flexible/wearable energy storage

A low-cost, light-weight, highly flexible supercapacitor is developed by using stainless steel mesh as electrode and commercial pen ink as active materials through a simple and efficient dip-coating method. The device demonstrates excellent flexibility with good electrochemical performance. The fabrication method is easily extended to industrial production for large scale flexible and wearable energy storage devices.
