Potassium ion battery slurry mixing process

The invention belongs to the technical field of battery manufacturing, and particularly relates to a potassium ion battery slurry mixing process which comprises the following steps: step 1, feeding an original powder material, adding the original powder material into a powder temporary storage tank, and conveying the powder into a rechecking and weighing tank through a screw feeding system in the powder temporary storage tank; and step 2, enabling the rechecked powder to fall into a screw kneading dispersion machine under the action of gravity. Compared with the traditional operation that stirring is completed completely through a double-planetary stirrer, a traditional mixing process is changed into staged mixing, in the first stage, a helical ribbon kneading and dispersing machine with the kneading capacity higher than that of the double-planetary stirrer is adopted for wetting and kneading raw powder materials, and in the second stage, the raw powder materials are kneaded and kneaded through a spiral ribbo
