porous wo3 graphene polyester Textile Electrode materials with enhanced electrochemical performance for flexible solid state supercapacitors
Journal of Colloid and Interface Science, 2018Co-Authors: Jianan Zhang, Shaowei BianAbstract:Abstract In this work, a flexible and porous WO3/grapheme/polyester (WO3/G/PT) Textile Electrode was successfully prepared by in situ growing WO3 on the fiber surface inside G/PT composite fabrics. The unique Electrode structure facilitates to enhance the energy storage performance because the 3D conductive network constructed by the G/PT increase the electron transportation rate, nanotructured WO3 exposed enhanced electrochemically active surface area and the hierarchically porous structure improved the electrolyte ion diffusion rate. The optimized WO3/G/PT Textile Electrode exhibited good electrochemical performance with a high areal capacitance of 308.2 mF cm−2 at a scan rate of 2 mV s−1 and excellent cycling stability. A flexible asymmetric supercapacitor (ASC) device was further fabricated by using the WO3/G/PT Electrode and G/PT Electrode, which exhibited a good specific capacitance of 167.6 mF cm−3 and high energy density of 60 μWh cm−3 at the power density of 2320 μW cm−3.

mno 2 nanotubes assembled on conductive graphene polyester composite fabric as a three dimensional porous Textile Electrode for flexible electrochemical capacitors
Journal of Colloid and Interface Science, 2017Co-Authors: Chun Jin, Jianan Zhang, Lina Jin, Meixia Guo, Ping Liu, Shaowei BianAbstract:Abstract A three-dimensional (3D) Electrode material was successfully synthesized through a facile ZnO-assisted hydrothermal process in which vertical MnO2 nanotube arrays were in situ grown on the conductive graphene/polyester composite fabric. The morphology and structure of MnO2 nanotubes/graphene/polyester Textile Electrode were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The 3D Electrode structure facilitates to achieve the maximum number of active sites for the pesudocapacitance redox reaction, fast electrolyte ion transportation and short ion diffusion path. The electrochemical measurements showed that the Electrode possesses good capacitance capacity which reached 498 F/g at a scan rate of 2 mV/s in Na2SO4 electrolyte solution. The Electrode also showed stable electrochemical performances under the conditions of long-term cycling, and mechanical bending and twisting.

high performance Textile supercapacitor Electrode materials enhanced with three dimensional carbon nanotubes graphene conductive network and in situ polymerized polyaniline
Electrochimica Acta, 2017Co-Authors: Fu Shao, Jianan Zhang, Shaowei BianAbstract:Abstract Three-dimension (3D) conductive network was successfully constructed by carbon nanotubes (CNTs) and graphene sheets (G) on the polyester fabric (PETC) using a “dipping-drying” process and electrophoretic deposition method, which facilitates to greatly enhance the electron transportation rate and shorten the electrolyte ion diffusion distance. The resultant composite fabric provides a promising substrate to prepare Textile-based Electrodes for flexile supercapacitors. After further coating the CNTs with polyaniline (PANI), the polyaniline/carbon nanotubes/graphene/polyester (PANI/CNTs/G/PETC) Textile Electrode exhibited high electrochemical performances. The composite Electrode showed a maximum areal capacitance of 791 mF cm −2 at a current density of 1.5 mA cm −2 . Compared to some reported PANI Electrodes with fast decay in capacitance capacity, the capacitance retentions of the composite Electrode was over 76% even after 3000 charge-discharge cycles. Moreover, the composite Electrode also exhibited stable electrochemical performances under the mechanical bending and stretching conditions.

mxene coated silk derived carbon cloth toward flexible Electrode for supercapacitor application
Journal of Energy Chemistry, 2018Co-Authors: Renfei Cheng, Jinxing Yang, Cong Cui, Chao Zhang, Xiaohui WangAbstract:Abstract Flexible supercapacitors are promising energy storage devices in wearable smart electronics. Exploring cost-efficient Electrodes with high capacitance would promote the wide-scale application of such capacitors. Herein, in order to explore a methodology for preparing low cost, flexible, tough, and up-scalable supercapacitor Electrodes, silk Textile is directly carbonized to make a conductive free-standing Textile substrate. Through mildly baking the surfactant-free Ti3C2Tx flakes suspension loaded on the carbonized silk cloth, a uniform and adhesive coating consisting of nanometer-thick Ti3C2Tx flakes is well established on the conductive fabric support, forming a MXene-coated flexible Textile Electrode. The fabricated Electrode exhibits a high areal capacitance of 362 mF/cm2 with excellent cyclability and flexibility. Moreover, capacitance changes neglegibly under the bending deformation mode. This study elucidates the feasibility of using silk-derived carbon cloth from biomss for MXene-based flexible supercapacitor.
