Description

Feeding equipment for high-viscosity slurry

Technical Field

The utility model relates to a thick liquids medium conveying equipment's technical field, concretely relates to a feeding equipment for high glutinous thick liquids.

The production of the lithium battery comprises a pole piece manufacturing process, a battery assembly process and a final liquid injection, pre-charging, formation and aging process. In the three-stage process, each process can be divided into several key processes, and each step can have great influence on the final performance of the battery. In the stage of pole piece manufacturing process, five processes of slurry preparation, slurry coating, pole piece rolling, pole piece slitting and pole piece drying can be subdivided. The pole piece manufacturing process is the core content of the whole lithium battery manufacturing, and is related to the quality of the electrochemical performance of the battery, and the quality of the slurry in the pole piece manufacturing process is particularly important.

The solid content of the slurry is closely related to the stability of the slurry, and the higher the solid content of the slurry is, the higher the viscosity of the slurry is and vice versa in the same process and formula. Within certain ranges, the higher the viscosity, the higher the slurry stability. The solid content has a certain influence on the improvement of the stirring efficiency and the coating efficiency. The higher the solid content is, the less the solvent is consumed, the higher the coating drying efficiency is, and the time is saved. Solid content has certain requirements on equipment, and the high-solid-content slurry has higher loss on the equipment, because the higher the solid content is, the more serious the equipment is abraded. The stability of the slurry obtained by the high-viscosity stirring process is superior to that of the conventional stirring process. However, high solids slurries also affect their flowability, making the coating process equipment and technicians very challenging. The slurry with high solid content can reduce the thickness between coatings and reduce the internal resistance of the battery.

The solid content of the existing electrode slurry is about 50%, and when the solid content of the electrode slurry is increased to more than 60%, the shape of the slurry is similar to a semisolid muddy object, and the fluidity of the slurry is obviously reduced. Due to the problem of poor fluidity of the slurry caused by high solid content, the transportation and defoaming of the slurry become significant problems.
