Wearable Carbon Nanotube Fibers for Energy Storage

Abstract

Wearable electronics are new developing technologies for energy storage in modern society, and they represent a new class of materials with an array of novel functionalities, such as flexibility, stretchability, and lightweight. We report the use of Carbon nanotube (CNT) fiber as weaved fabric electrodes for this kind of wearable energy storage applications. This CNT fabric is composed by all pure CNTs. The weaved CNT fabric offers many advantages such as large active specific surface areas, high electrical conductivity, improved electron transfer as well as high chemical stability, and the capacitance of our CNT fabric is about 60-80 F g-1 whose value is the highest in the same kind of CNT fabrics. Our CNT fabric can adapt to wearable electronics such as wearable solar cells and batteries, high-performance sportswear, wearable displays, new classes of portable power etc.
