A kind of preparation method of metal-carbon nanotube composite porous electrode material

Abstract

The invention discloses a preparation method of a metal-carbon nano tube compounded porous electrode material. The preparation method comprises the following steps: depositing a transition metal layer on a porous metal material, and then growing carbon nano tubes on the transition metal layer by taking the transition metal layer as a catalyst. The preparation method has the advantages that the carbon nano tubes growing on the porous substrate have less impurities, and are uniform, orderly, and high in consistency; the prepared electrode material is high in specific surface area and conductibility, and long in service life; the preparation process of the material is stable and efficient, so that convenience is brought for continuous production.

technical field

[0001] The invention relates to a preparation method of a porous electrode material, in particular to a preparation method of a metal-carbon nanotube composite porous electrode material. Background technique

[0002] Electric energy is an indispensable secondary energy in human life and production in modern society. With the continuous development of social economy, its proportion is getting higher and higher. At present, in order to cope with the depletion of fossil energy and for the consideration of environmental protection, people are developing and utilizing renewable clean energy such as wind energy, water energy, and solar energy more and more widely. However, due to the limitation of natural conditions, the use of wind energy and Solar power generation is intermittent and not continuous. While reducing the construction scale of original power plants and increasing the proportion of renewable energy systems, in order to meet people's production and li...
