Abstract: Carbon nanotubes have a one-dimensional tube-like structure with superior electrical and thermal conductivities, as well as mechanical strength. Such a structure makes it suitable for using as the backbone of flexible electrodes and long distance electrically conductive networks, and for creating high reactive surface area for overall performance. As a result, carbon nanotubes have attracted tremendous interest for due to numerous potential applications in the field of energy storage. This article reviews the work on the use of carbon nanotubes in flexible energy storage devices, covering supercapacitors, lithium ion batteries and lithium sulfur batteries. We will show that although there have been considerable amount of research on flexible supercapacitors and lithium ion batteries, little has been done on flexible lithium sulfur batteries. and rapid progress is expected to occur in the near future. In addition, we also briefly cover fabrication of flexible electrodes, and introduce criteria for evaluating electrode performance.
