Abstract

original image

A novel type of flexible fiber/wearable supercapacitor that is composed of two fiber electrodes – a helical spacer wire and an electrolyte – is demonstrated. In the carbon-based fiber supercapacitor (FSC), which has high capacitance performance, commercial pen ink is directly utilized as the electrochemical material. FSCs have potential benefits in the pursuit of low-cost, large-scale, and efficient flexible/wearable energy storage systems.
