Abstract

The invention discloses a continuous dispersion device used for lithium-ion battery slurry. The device includes at least one powder substance storage tank, at least one solvent storage tank, at leastone first grade primary dispersing mechanism and at least one first grade centrifugal dispersing mechanism; the discharging ports at the bottoms of each powder substance storage tank and each solventstorage tank communicate with at least one first grade primary dispersing mechanism through pipelines; and the discharging ports of the first grade primary dispersing mechanisms communicates with at least one first grade centrifugal dispersing mechanism. The device can respectively put powder substances and liquid substances and adopt a spraying mode to put the liquid substances, and dispersing effects can be enhanced by performing primary dispersing and centrifugal dispersing on materials; and the continuous work of slurry can be realized by arranging the primary dispersing mechanisms into three grades and arranging the centrifugal dispersing mechanisms into two grades, so that the slurry can be uninterruptedly produced, and dispersing quality and production efficiency can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of lithium-ion battery slurry manufacturing, and in particular relates to a continuous dispersion device for lithium-ion battery slurry. Background technique [0002] Lithium-ion battery is a green and high-energy rechargeable battery, which has broad application prospects in portable electronic devices, electric vehicles, energy storage, and defense industries. The mixing and dispersion of lithium-ion battery slurry is a very important link in the entire production process of lithium-ion batteries. The quality of slurry dispersion will directly affect the quality of subsequent lithium-ion battery production and the performance of its products. With the continuous advancement of lithium-ion battery materials, the particle size of raw materials is getting smaller and smaller, which not only improves the performance of lithium-ion batteries, but also easily forms secondary aggregates, which increases the diffi...
