Problems solved by technology

Compared with supercapacitors with rigid structures, flexible supercapacitors have a wider range of applications. However, these flexible batteries are still based on a two-dimensional planar sandwich structure, so their applications in some fields are still limited, such as their portability. Sex or special space restricts its assembly, etc.

Abstract

The invention discloses a fibrous chemical energy storage power supply and a preparation method thereof. The fibrous chemical energy storage power supply comprises a fiber anode, a fiber cathode, electrolyte, diaphragm fiber and an outer packaging layer. The fiber anode (fiber cathode) comprises a conductive filamentous base and an electrochemical active material coated on the conductive filamentous base. The diaphragm fiber is formed by winding insulated fiber on the surface of one working electrode at a certain screw pitch so that short circuit caused by the direct contact of two electrodes is avoided. The fiber anode and the fiber cathode can be wound with each other or arranged in parallel and are arranged in the outer flexible packaging layer, and the electrolyte is filled between the outer packaging layer and the two working electrodes. The fibrous chemical energy storage power supply not only can realize efficient energy storage, but also can endow an energy storage battery with favorable flexibility and portability. What deserves to be mentioned the most is that the invented fibrous chemical energy storage power supply is suitable for all types of chemical energy storage power supplies, and the power supply ways in the life are greatly enriched.
