Description

Technical Field

[0001] This utility model relates to the field of carbon nanotube slurry production technology, specifically to a production device for carbon nanotube conductive slurry. Background Technology

[0002] Carbon nanotube conductive slurry is a slurry with good conductivity, made by adding carbon nanotubes as the main conductive component and auxiliary materials such as dispersants and solvents. Carbon nanotubes are one-dimensional quantum materials formed by single or multiple layers of graphene rolled around a central axis at a certain helical angle. Adding carbon nanotube conductive slurry to the positive and negative electrode materials of lithium-ion batteries can improve the conductivity of the electrodes, reduce the internal resistance of the battery, and improve the charge and discharge efficiency, energy density, and cycle life of the battery. Especially in the development of high-energy-density batteries and fast-charging batteries, carbon nanotube conductive slurry plays an important role. However, the production of carbon nanotube conductive slurry requires a carbon nanotube conductive slurry production device. In order to make the viscosity of carbon nanotubes more stable, auxiliary solvents need to be added. However, existing slurry production devices cannot measure the dosage of added auxiliary agents and cannot better guarantee the viscosity during the production and processing of carbon nanotubes. Therefore, this utility model proposes a carbon nanotube conductive slurry production device to solve the above problems. Utility Model Content
