Background

In the field of new energy, a lithium battery is a new field, and the preparation and production of lithium battery slurry is a very important part of the transition from a lithium battery raw material to a lithium battery finished product, and has a great influence on the charging and discharging process of the lithium battery and the performance of the lithium battery.

At present, lithium battery slurry is produced by adopting a traditional gap type stirrer, most of the lithium battery slurry is prepared into glue solution by using an adhesive, and then powder and other materials are gradually added in the production process. The intermittent production mode has low efficiency, in addition, the production time is prolonged by adopting the glue solution prefabricating mode, the production efficiency is lower, the production cost is high, the viscosity of the slurry can not be controlled by each batch of slurry, and the consistency and the uniformity of the slurry are poor.

For example, the Chinese patent application No. CN201821155731.3 is a full-automatic continuous production system for lithium battery slurry, the adhesive can be directly added into the continuous production system, the adhesive is not required to be used for preparing glue solution, and the production efficiency is improved.
