Conductive textiles represent a crucial class of smart textiles with promising future applications in electronic textiles, display devices, health monitoring devices, thermal and moisture management, flexible energy storage, and power generation devices. Recently, remarkable attention has been devoted to developing textile supercapacitor for energy storage and wearable electronics applications. Supercapacitor textiles offer lightweight, flexibility, stretchability, and ease of integration with electronic textiles.
Recently researchers have developed flexible supercapacitors on a PC fabric. Flexible and fully encapsulated supercapacitor fabricated on top of polyester-cotton, which demonstrated area capacitance of 0.54 mF·cm−2 and a normalized ESR of 1.2 kΩ.cm−2. The proposed devices were electrochemically stable between +/−1.8 V and exhibited a negligible difference in CV tests between the bent and non-bent devices.
Compared with other works, these results are not as good as the encapsulated supercapacitor fabricated in the polyester-cotton textile with the copolymer membrane in the fabric as a separator and activated carbon as electrodes. However, it demonstrates the feasibility of the materials and fabrication processes and the assembly approach which has successfully realized an encapsulated supercapacitor on top of the polyester-cotton textile. Future work will include optimizing the electrode’s formulation and fabrication process and the electrolyte for better electrochemical performance.
