Abstract

The invention belongs to an activation method of a carbon fiber electrode material. The invention adopts polypropylene carbon fiber weaved cloth soaked with epoxy resin as a raw material, and comprises the following steps of injecting air in a short time at a low vacuum condition with a temperature 600-700 DEG C, then performing vacuumization and natural cooling; thereby the surface properties of the carbon fiber cloth are improved, and the electrode activity is increased by more than 3 times.

Description

[0001] technical field

[0002] The invention belongs to an activation method of a carbon fiber electrode material using polyacrylonitrile carbon fiber. Background technique

[0003] Carbon fiber products have a series of useful properties such as good corrosion resistance, electrical conductivity, and porosity.

[0004] physical and chemical properties. It can be used as an electrode or auxiliary material for various types of batteries, and is one of the basic materials for the development of new energy storage batteries. However, the electrochemical activity of untreated carbon fibers is limited. For example, the chromium negative electrode reaction of iron-chromium redox flow batteries can only be active when loaded with precious metal catalysts such as gold or after special treatment such as high temperature. The United States has studied the influence of different carbon fiber felts, different carbonization temperatures, chemical purification treatments, and different...
