Problems solved by technology

The conductive electrode constructed by it has the following defects: one, carbon nanotubes are easy to aggregate, and only rely on the hydrogen bond and van der Waals force between cotton fibers and nanocarbon materials (such as carbon nanotubes, graphene, etc.) to combine its fastness is poor and not easy to be uniform
Third, the stretchability of pure cotton fiber itself is poor, and it needs to be blended or interwoven with other fibers with better elasticity to form a stretchable electrode

Description

technical field [0001] The invention belongs to the field of electrode materials and preparation thereof, in particular to a preparation method of a three-dimensional carbon nanotube / textile fiber stretchable electrode material. Background technique [0002] Electrochemical capacitors, also known as supercapacitors, are a new type of energy storage device that combines the performance of conventional capacitors and rechargeable batteries. Due to the advantages of high power density, long cycle life, fast charging speed, long storage time, good temperature characteristics, green safety, etc., it is known as the most potential energy storage device in the 21st century. Traditional power sources such as batteries and supercapacitors are all solid structures, which are too rigid. At present, the flexible supercapacitors that have been studied more have certain flexibility, but basically do not have stretchability, that is, they cannot achieve large deformation similar to textil...
