A high-performance, customizable, wearable and foldable solid-state supercapacitor realized by arranging pseudo-capacitance groups and MXene sheets on the surface of textile electrodes. First author: Yuanming Wang Corresponding author: Li Xifei*, Yuan Guohui* Unit: Harbin Technical University


Research Background
So far, a large number of flexible electrochemical energy storage devices are directly built on various types of flexible substrates, such as graphene paper, carbon tube (CNTs) films, metal plates and textile materials. Among them, textile-based electrochemical energy storage devices (TEESDs) have many attractive features. Flexible solid-state supercapacitors (SCs) are particularly competitive among these TEESDs as an alternative to emerging power sources, but at the same time, they also have the special characteristics of high power density and safety. However, current solid-state SCs still face challenges to maintain the balance between electrochemical performance, mechanical stability and processing technology.
Article Introduction
Recently, Li Xifei of Harbin Institute of Technology cooperated with Professor Yuan Guohui and others. Published research work titled "A High-Performance, Tailorable, Wearable, and Foldable Solid-State Supercapacitor Enabled by Arranging Pseudocapacitive Groups and MXene Flakes on Textile Electrode Surface" in the international journal Advanced Functional Materials. This work developed a high-performance, customizable and foldable solid asymmetric supercapacitor through a step-expanded chemical oxidation and N-doped carbon fiber fabric (NCFT) substrate MXene ink spraying.
