Problems solved by technology

As the core component of lithium-ion batteries, battery electrodes have higher and higher performance requirements. However, the existing lithium-ion battery electrode materials still have problems such as poor mechanical properties, low conductivity, easy aging, and high preparation costs.
[0004] Conductive polymers are a class of polymers with conjugated structures. Chemical, electrochemical or ion doping can make the electrical conductivity of polymers from insulating level to metal level. However, most of the rubber materials currently used are relatively insulative. Well, some are also used as insulation sheath material, therefore, the purpose of the present invention is to change the service performance of traditional rubber material, provide a kind of macromolecule conductive composite rubber material, it has improved the mechanical strength of finished product and conductive stability, and It has good anti-aging performance and good weather resistance, which enhances the application range of rubber powder

Abstract

The invention discloses anti-aging conducting rubber powder. The anti-aging conducting rubber powder comprises the following raw materials in parts by weight: 0.8-1 part of ammonium persulfate, 120-130 parts of waste rubber powder, 2-3 parts of an anti-aging agent rd, 3-5 parts of acetic anhydride, 0.01-0.02 part of a catalyst, 30-40 parts of aniline, 10-12 parts of an organic filler, 1-2 parts ofdodecyl trimethyl ammonium chloride and 3-4 parts of zinc stearate. The rubber powder has very good anti-aging performance, good wear resistance and certain electrical conductivity, so that the application range of the rubber powder is increased.

Description

technical field [0001] The invention belongs to the field of lithium-ion battery electrode materials, and in particular relates to an anti-aging conductive rubber powder and a preparation method thereof. Background technique [0002] Now, for not releasing any polluting gases like CO 2 , NO x , hydrocarbons and the like, there is an urgent need to develop a rechargeable battery with high energy density. Also, there is an urgent need to develop a miniature, lightweight and highly efficient rechargeable battery for use as a power source for portable devices such as small personal computers, digital cameras, and mobile phones. [0003] As such a small, lightweight, high-efficiency rechargeable battery, various lithium-ion batteries have been proposed. Lithium-ion batteries are composed of a positive electrode and a negative electrode, which have the property of reversibly deintercalating lithium ions, and a non-aqueous electrolyte. As the core component of lithium-ion batter...
