Abstract

The invention belongs to the technical field of preparation and application of graphene, and specifically provides a graphene conductive agent. The graphene conductive agent comprises the following components in parts by mass: 70-100 parts of graphene, 30-80 parts of epoxy resin, 10-20 parts of monoethanolamine, 10-20 parts of triethylene tetramine, 10-20 parts of water, 20-30 parts of ethyl alcohol, 12-15 parts of butyrolactone, 12-18 parts of N, N-diethyl ethylene diamine, 5-10 parts of acetone, 10-20 parts of tetrahydrofuran, 2-5 parts of hydroxyethyl cellulose, 1-3 parts of chitosan, 2-6 parts of seaweed mud, 2-8 parts of silane coupling agent, and 5-30 parts of carbon nanotube. According to the graphene conductive agent, a small number of carbon nanotubes are introduced; the capacityof an electrode material is improved based on high conductivity of graphene and the carbon nanotube; the internal resistance of a battery is reduced; and the cycle life of the battery is prolonged while the conductivity of the conductive agent is improved.

Description

technical field [0001] The invention belongs to the technical field of graphene preparation and application, in particular to a graphene conductive agent. Background technique [0002] Lithium-ion batteries have the incomparable advantages of nickel-metal hydride and nickel-cadmium secondary batteries such as large specific capacity, high and stable discharge voltage, good low-temperature performance, environmental friendliness, safety, long life, and weak self-discharge. Since its inception in 1991, after years of development, lithium-ion batteries have dominated the market for small portable batteries, such as the well-known batteries for mobile phones, notebook computers, and small video cameras. With the improvement of the performance of lithium-ion batteries, lithium-ion batteries will surely enter the market of large-scale power batteries in time, such as batteries for electric vehicles. Lithium batteries are relatively small in size and have higher requirements on th...
