Abstract

The invention provides an electrode material made of waste fibers and belongs to the field of electrode materials applied to electrochemical reaction. The electrode material made of the waste fibers comprises basic materials, wherein the basic materials are fiber materials which are formed by carbonization of the waste fibers after the waste fibers are burnt at a high temperature, the waste fibers are burnt at the high temperature in a vacuum furnace or under the protection of the inert atmosphere, surface treatment is carried out finally, and the basic materials are formed by one or more of polypropylene cyanide fibers, pitch fibers, viscose, pre-oxidized fibers, phenolic fibers, carbon fibers, graphite fibers, wood fibers and cotton fibers. According to the electrode materials made of the waste fibers, due to the fact that the waste fibers are used, cost is reduced, benefit of an enterprise is improved, the competiveness of products is improved, and the electrode material is high in conductivity and high in electrochemical activity.

Description

technical field [0001] The invention relates to the application of waste fiber materials, in particular to an electrode material made of waste fiber and used in electrochemical reactions and a processing and manufacturing method for the electrode material. Background technique [0002] Electrode materials are widely used in batteries, water treatment, seawater desalination, electroplating, metallurgy and other fields, and are mainly used as electrodes for electrochemical reactions. However, with the expansion and popularization of the product application range, the performance and structure requirements of the equipment are becoming more and more stringent and complex, including higher reaction temperature, stronger corrosion resistance, larger volume, and lighter weight. Weight, greater capacity, higher power, higher efficiency and other technical advantages. For example, in the manufacturing process of liquid vanadium batteries, larger size, higher efficiency, and larger ...
