Flexible Coated Textiles as Supercapacitors

Written by:

Energy storage devices like batteries and supercapacitors are playing a prominent role in meeting our global energy management for greener and more energy balanced world. Hence building a lightweight supercapacitor which is expected to meet future energy needs is important. Textiles are known for their lightweight, porosity, high surface area and other properties which perfectly meet the requirements for building a supercapacitor. Fabrics must be imparted with charge storage ability by coating materials which have superior capacitance values. Conducting polymers, Carbon nanotubes, metal oxides are conductive materials which would give charge storing ability to textiles when coated. A brief overview about supercapacitors and above said conductive materials with their capacitance principles is given in this article.


The power requirements for a number of portable' electronic devices have increased markedly in recent years and have exceeded the capability of conventional batteries to such an extent that great attention is being focused on electrochemical supercapacitors (SCs) as energy storage systems. Energy storage devices are classified according to energy and power density. Power density is related to the "strength" (wattage) of a given current and voltage combination, while energy density is related to the "duration" of time that wattage can be applied.
