Pumps for lithium battery industry

The lithium industry (lithium battery manufacturing industry) is a highly technology-intensive industry involving several complex production processes, such as electrode preparation, electrolyte injection, and battery encapsulation. In these processes, pumps, as key fluid transfer equipment, are widely used in the transfer, metering and circulation of various liquids and slurries. As lithium battery production requires high process precision, cleanliness and safety, pumps for the lithium industry need to be characterized by high precision, corrosion resistance and non-pollution.

Solutions for various application requirements

• High viscosity battery adhesive conveying: battery production process of battery electronic adhesive and other high-viscosity materials, the choice of large-size rotor, optimized clearance pumps, with low-speed motors, reduce the speed to reduce the shear force on the adhesive liquid, to avoid destroying the structure of the active substance, to effectively meet the requirements of material transport;
• High solid content slurry conveying: battery electrode production, the need to transport lithium cobalt, graphite, and other high solid content slurry. High solid content slurry conveying: In the production of battery electrode, it is necessary to convey lithium cobaltate, graphite and other high solid content slurry. At this time, the selection of the appropriate size of the rotor, optimize the gap between the rotor and the pump body of the cam rotor pump, while spraying tungsten carbide coating of the pump, to reduce the wear and tear of the material on the pump;
• corrosive electrolyte conveying: the electrolyte contains lithium salts, organic solvents and other corrosive components. Pump body and rotor should be used such as 316L, 2205, 2507, Hastelloy and other corrosion-resistant materials, seals with polytetrafluoroethylene (PTFE), perfluoroelastomer and other cam rotor pumps. Long-term stable operation is guaranteed.
• Waste disposal: Battery production generates waste containing heavy metals and chemical substances. We choose a cam rotor pump made of wear-resistant material and install a coarse strainer at the inlet to prevent clogging by impurities in the waste material and resist particle abrasion. Such pumps are used to transfer the waste materials to the recycling and processing equipment when dealing with waste electrode materials.
