Wearable textile-based energy storage devices are the energy storage that make use of and/or shaped into textile fibers, yarns, and fabrics, which are promising for wearable electronic applications. To date, the major challenge in the development of wearable energy storage devices is how to improve the electrochemical properties of the device while acquiring high flexibility and durability under different wearing conditions. Recently, our laboratory has developed several energy storage yarns and fabrics through utilizing various low-dimensional and nanoscale materials, which show record−high electrochemical performances as well as excellent flexibility of their kinds. These textile−based devices can be readily integrated into different textile forms by means of weaving, embroidery, and heat pressing for wearable applications.
