Abstract

The invention relates to a breathable symmetrical flexible all-solid-state super capacitor and a preparation method thereof. The super capacitor is prepared through the steps of (1) taking an oxidant and a dopant in deionized water to obtain a mixed solution A, then transferring to a culture dish containing pre-treated dust-free paper, and performing low temperature pretreatment; (2) dispersing pyrrole monomers in n-hexane, and performing low temperature pretreatment to obtain a mixed solution B; (3) adding the mixture B dropwise to the culture dish, and allowing static reaction; (4) taking out a reaction product, and washing and drying to obtain an electrode material; (5) immersing two pieces of the same electrode material into a gel electrolyte again, taking out the two pieces of electrode material respectively as positive and negative electrodes being in face to face placement, then coating the middle with a layer of gel electrolyte again, and drying to obtain the super capacitor. Compared with the prior art, the super capacitor of the invention has the characteristics of excellent electrochemical performance, good air permeability, flexible performance, simple operation, mass production and the like.

Description
