[0002] Because of its unique two-dimensional layered structure, graphene endows it with a high theoretical specific surface area and ultrafast electron mobility, making it a flexible electrode material; at present, the research and development of flexible electrochemical capacitors and electrode materials has become a International hotspot, there have been a lot of research on how to improve the wearing comfort of wearable energy storage devices and how to improve the electrochemical performance at home and abroad, but the high production cost, poor flexibility, low durability and environmental dependence Sex etc. limit their real application
Carrying new materials and designing new structures are important methods to improve the performance of wearable energy storage devices and improve their environmental adaptability, and textile materials are one of the materials that are very suitable. Textile materials are natural wearable materials, which give people the impression and reality. The application of flexible electrode materials is very comfortable and soft, but due to the particularity of the material and surface properties of textile materials, there are certain shortcomings and problems in the application of flexible electrode material technology. Therefore, we propose a fiber graphene Preparation method of copper sulfide flexible electrode material
