Carbon base porous electrode film used in super capacitor and its preparation method

Abstract

The invention is a carbon base porous electrode film for super capacitor and the preparing method thereof. And the composition contents of the film: activated carbon 72 mass%-99mass%, conducting carbon black or graphite 0.1mass%-20mass%, zirconium oxide nano powder 0.1mass% -5mass%, and nano metallic Ni powder 0.1mass%-3mass% and the gas ratio of the film is 45%-75% and the preferential one is 55%-65%. The method firstly uniformly mixes deionized water and organic monomer with cross-linking agent; then adds dispersant in the solution and blends uniformly to obtain a preset solution; then adds in raw materials and makes ball-milling mixing to make the pulp; adds defoaming agent in the pulp for vacuum defoaming; then adds in initiator and catalyst and blends uniformly, then obtains raw blanks on a casting machine by molding, curing and defilming, and then makes weak oxidizing atmosphere thermal treatment to obtain the target porous electrode film. The invention has simple molding process, short molding time, easy operation, good film thickness controllability, and developed medium holes.

Description

technical field

[0001] The invention relates to a composite carbon-based porous electrode film and a preparation method thereof, in particular to a composite carbon-based porous electrode film for supercapacitors and a preparation method thereof. technical background

[0002] As one of the pillar industries of modern human civilization, energy has been paid more and more attention by people. At the same time, the environmental problems caused by the emission of various waste gases produced by energy and the greenhouse effect have become the most concerned hot spot in the world, and it is also an increasingly profound social problem. Harsh environmental pollution not only poses a serious threat to human and biological living space, but also leaves endless hidden dangers for future generations. Scientists and people of insight all over the world have appealed to governments and industrial departments of various countries to protect the earth's environment and the living space...
