During the production process of lithium batteries, lithium iron phosphate is generally mixed with a conductive agent and a binder through a raw material mixer to form a mixed raw material, and then coated to become the positive electrode of the lithium battery.

[0003] Before stirring the battery production raw materials, the raw materials are first injected into the stirring barrel according to a ratio, and stirred by a stirring mechanism arranged in the stirring barrel. After stirring, they are sent to a filtering device for filtering to remove impurities to prevent the impurities from affecting subsequent processing and battery quality. After filtering, they are sent to the next process for processing.
