Ultrasonic Dispersion Equipment in Battery Area

The dispersion and stabilization mechanism of lithium battery slurry, according to the force type of particles in the slurry, the main methods to achieve uniform dispersion of lithium battery slurry include: mechanical dispersion (or physical dispersion), ultrasonic dispersion and chemical dispersion (dispersing agent). dispersion) in three ways. Mechanical dispersion is a simple physical dispersion. It mainly uses mechanical energy such as external shear force or impact force to destroy the adhesion between particles, so that the powder particles are fully dispersed in the medium. Mechanical dispersion is currently the most widely used dispersion method. Ultrasonic dispersion is to directly place the battery slurry to be treated in an ultrasonic field, and use ultrasonic waves of appropriate frequency and power to process the slurry. The basic principle of ultrasonic dispersion is related to the cavitation effect. The surface energy of powder particles is weakened under the action of huge impact force and micro-jet, which can effectively prevent particle agglomeration. Therefore, ultrasonic dispersion is a high-strength dispersion method. Chemical dispersion uses the adsorption of inorganic dispersants on the particle surface, which not only significantly increases the Zeta potential of the particle surface, but also forms a strong steric hindrance effect, so that the particles in the slurry are uniformly dispersed.

The colloidal battery ultrasonic dispersing and pouring device is used to make the colloid evenly dispersed in the battery, so as to ensure the quality of the produced battery is stable and the pass rate is high. At the same time, it does not affect the production efficiency while ensuring the production quality. In order to solve the above problems, the utility model is realized by the following technical solutions: a colloidal battery ultrasonic dispersion glue filling device, including a vacuum acid adding machine, the battery to be processed is placed on the working table of the vacuum acid adding machine, and the battery is facing the vacuum acid adding machine. The acid pipe of the machine is equipped with an ultrasonic generator under the battery. With this structure, the colloid in the battery can be ultrasonically dispersed by an ultrasonic generator while adding acid. Compared with the prior art, the utility model has the advantages of dispersing the colloid in the battery through the ultrasonic dispersing step, avoiding the problems of unstable battery quality and low yield due to uneven dispersion of the colloid, and making the qualified rate of the finished product high.
