Abstract

Recently, researchers have become interested in exploring applications of rechargeable battery storage technology in different disciplines, which can help our daily life, such as textile-based supercapacitors. This paper briefly describes this development and classification of supercapacitors. Besides, various types of materials which are commonly used to prepare supercapacitors, such as carbons, metal oxides, alkaline earth metal salts and polymers, are introduced. Moreover, applications and methodology to prepare textile materials with supercapacitors are described. Finally, the commonly used non-destructive measuring methods for textile-based supercapacitors are also introduced.

Highlights

  • In recent years, significant effort has been committed to alternative energy storage/conversion devices development with high energy and power densities due to the increase of environmental problems and the continuing depletion of fossil fuels

  • electrical double-layer (EDL) capacitors consist of activated carbon (AC) with higher surface area used as the electrode material, and the capacitance comes from charges which are accumulated at the interface between the electrode and the electrolyte

  • The highly flexible structure of textile materials is viewed as an advantage by researchers, and they continue to explore the preparation of supercapacitors for various applications in textile materials made of natural and synthetic fibers, such as cotton and polyester, respectively, or even carbon fibers

Summary

Introduction

Significant effort has been committed to alternative energy storage/conversion devices development with high energy and power densities due to the increase of environmental problems and the continuing depletion of fossil fuels. As an intermediate system between batteries and dielectric capacitors, supercapacitors have attracted an extensive attention owing to their higher power densities relative to secondary batteries. They are maintenance-free, have a longer life cycle, can cope with a simple charging circuit, suffer no memory effects and are generally safer to be used. It is applicable to different complex-shaped materials or non-conducting substrates, it can be applied to most kinds of fiber substances This plating can be done at any stage during textile production, such as fiber, yarn, fabric and garment [7]. Fabric-based supercapacitors are discussed in terms of material characteristics, preparation methods and characterization methods
