AI Technical Summary

Problems solved by technology

The use of conductive fibers as the positive electrode of rechargeable batteries has attracted widespread attention in the world. At present, although conductive fibers have high conductivity and good flexibility, their mechanical strength is generally not high, and they usually do not have antistatic properties.

Abstract

The invention discloses antistatic methyl fiber. The antistatic methyl fiber comprises the following raw materials in parts by weight: 2-3 parts of barium stearate, 5-7 parts of triethylene glycol diisooctanoate, 190-200 parts of acrylonitrile, 3-4 parts of dicumyl peroxide, 0.4-1 part of 8-hydroxyquinoline and 40-50 parts of an antistatic methyl emulsion. The acrylonitrile is used as a monomer, the antistatic methyl emulsion is used as a reaction solvent, and through polymerization under the action of an initiator, the dispersion compatibility of carbon black between fibers is improved and the mechanical strength of the finished fiber is improved; the antistatic methyl fiber is high in toughness, good in antistatic performance and excellent in overall performance.

Description

technical field [0001] The invention belongs to the field of rechargeable batteries, and in particular relates to an antistatic methyl fiber and a preparation method thereof. Background technique [0002] In recent years, electronic devices, especially mobile devices such as mobile phones, personal digital assistants, and notebook computers, have gradually become smaller, lighter, thinner, and higher in performance. With the diversification of the range of utilization of such mobile devices, rechargeable batteries to drive them have become very important components. [0003] As the key components of rechargeable batteries, the positive and negative electrodes not only need to have high electrical conductivity, but also need high mechanical properties and antistatic properties. At present, there is little progress in the research on improving the mechanical properties and antistatic properties of rechargeable battery electrodes. There are reports. The use of conductive fibe...
