AI Technical Summary
During the slurry production process, especially when dispersants are added to high-viscosity liquids, a large number of microbubbles are generated, which are difficult to eliminate naturally, affecting the uniformity of battery coating and leading to battery safety issues.
A dual defoaming device is adopted, combining a vibrator and an ultrasonic vibration module. Larger bubbles are broken up by high-frequency vibration, and tiny bubbles in the slurry are eliminated by staged filtration using a filter screen and filter cylinder.
It improves the separation of bubbles and slurry, ensures coating uniformity, enhances battery safety and performance stability, and avoids potential secondary contamination of slurry by traditional methods.
