The mass of the battery is 70% related to the quality of the pole piece, and the mass of the pole piece is 70% related to the quality of the slurry. Therefore, the slurry is prepared to be equal to 50% of the prepared battery, which is the first work and the core work of battery manufacture. Well-mixed slurries are very fluid with excellent flow properties, while well-flowing fluids have the most common characteristics of fluids-good surface tension of liquids. The tension makes the liquid edge gather to the inside to repair the concave-convex shape of the liquid interface. The good fluidity of the slurry makes it a fluid with tensile properties: the surface tension of the fluid causes the trailing serration interface to converge and converge towards the inside of the fluid, reducing the amplitude of the serrations.
The improvement of the slurry quality not only greatly helps the coating effect, but also has critical improvement on the battery quality. However, the production yield is gradually increased, more and more problems are exposed in the actual coating process, large particles, broken foils and other impurities below a scraper blade in the coating process often occur in the production process, the scraper is broken and damaged, the aluminum foil is scraped and scrapped, and the slurry is settled to influence the performance of the carbon-coated aluminum foil, so that the improvement of a slurry circulating system is urgently needed, and the problems are avoided. The main points are as follows: 1. settling the slurry in a material cylinder; 2. the slurry has large particles and impurities, so that the coating effect is poor, and the battery is influenced. In order to prevent the battery performance from being caused by coating, it is a primary task to improve the coating quality, and therefore, it is necessary to improve the excess impurities present in the slurry.
