Abstract

The invention provides a fibrous supercapacitor and a manufacturing method thereof. The supercapacitor comprises first working electrodes, second working electrodes, electrolyte, isolation fibers and an outer packaging layer, wherein the working electrodes comprise filamentous conductive substrates and electrochemical activity material layers coated outside the filamentous conductive substrates; the isolation fibers are wound on the surface of the first working electrodes; the second working electrodes and the first working electrodes form a parallel or wound structure; the electrolyte is filled between the working electrodes and is clad in the outer packaging layer with the working electrodes; and one or more first working electrodes and second working electrodes are arranged. The fibrous supercapacitor has high flexibility and portability, high-efficiency energy storage can be realized, the power forms in people's life are greatly enriched, and an accumulator in a special form can be provided for special cutting-edge fields.

Description

technical field

[0001] The invention belongs to the field of supercapacitors in chemical energy storage power sources, in particular to a flexible, weavable and portable fibrous supercapacitor and a preparation method thereof. Background technique

[0002] The excessive use of fossil energy by human society has led to the deterioration of environmental problems and directly affected the sustainable development of human beings. Therefore, it is particularly important to develop green energy and high-efficiency energy storage devices. Supercapacitor is a kind of high-efficiency energy storage device based on electrochemical double layer, which has attracted more and more attention from the scientific and industrial circles. Compared with chemical batteries (such as lithium-ion batteries, nickel-metal hydride batteries, etc.), supercapacitors have better power output capabilities, which makes supercapacitors more important in certain fields such as electric vehicles. In recen...
