Abstract

The invention discloses a super capacitor fiber electrode and a manufacturing method of the super capacitor fiber electrode. The fiber electrode comprises a conductive fiber and multiple layers of nanometer particles which are deposited on the conductive fiber, and hole-shaped structures are formed among the multiple layers of nanometer particles. Electrochemical deposition is adopted in the super capacitor fiber electrode to obtain a multi-hole grapheme-carbon sphere laminated structure on the surface of a platinum wire with the diameter being 100 micrometers, therefore the super capacitor fiber electrode has double-layer capacitance effects, satisfies the demands of manufacturing fiber-shaped super capacitors, and is long in cycle life.

Description

technical field [0001] The invention relates to the technical field of supercapacitors, in particular to a supercapacitor fiber electrode and a preparation method thereof. Background technique [0002] According to the different energy storage methods of supercapacitors, supercapacitors are divided into three types: electric double layer capacitors, pseudocapacitors, and hybrid capacitors of the above two types of capacitors. Among them, the electrode materials of electric double layer supercapacitors are mainly carbon materials, including activated carbon, carbon aerogel, carbon nanotubes, and graphene oxide. As the electrode material of the electric double layer capacitor, it needs to have good conductivity and large area, etc., and graphite has such characteristics, so graphite is selected as the electrode material of super capacitor. [0003] The supercapacitor electrode preparation method in the prior art mainly includes two kinds: [0004] 1. Carbon spheres (200 nano...
