Especially with the rapid development of information and microelectronics industries, the advent of a large number of industrial and civilian portable electronic products, the research and development of electric vehicles, and the enhancement of environmental protection awareness, people have an urgent need for batteries that are small in size, light in weight, high in energy, safe and reliable, and can be recharged repeatedly.

[0003] Under this circumstance, new power lithium-ion batteries have developed rapidly. The preparation and production of lithium battery slurry is a very important part of the transition from lithium battery raw materials to lithium battery finished products, which has a significant impact on the charging and discharging process of lithium batteries and the performance of lithium batteries.

[0004] At present, the preparation of lithium-ion battery slurry in China is basically completed in a dual planetary dispersion device after manual batching. Although the production technology of small batteries has become increasingly mature, the consistency control of batteries in the production process of lithium-ion batteries is still a technical difficulty in the production of lithium-ion batteries, especially for large-capacity and high-power power lithium-ion batteries. 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 agglomerates, thereby increasing the difficulty of the mixing and dispersion process.

After the auxiliary material (glue making) is stirred, it is transported to the mixer through pipelines with the powder main material, liquid solvent (NMP, deionized water) and liquid auxiliary materials for mixing and dispersion.
