Product inquiry

The rapidly growing share of electric vehicles is leading to a very high demand for lithium-ion batteries. In order to meet the demand for long ranges, the quality and performance requirements for batteries and their production processes are also constantly increasing. Vacuum components from Schmalz meet the high demands of the industry and are used in automated cell production and module assembly. In addition to automation technology, Schmalz also offers vacuum lifters and crane systems for the ergonomic and safe handling of heavy battery modules.

Contamination

Suction surface made of special material PEEK (polyetherether ketone) minimizes mechanical abrasion and prevents chemical contamination. The high volume flow of gripper also removes particles from the electrode, which are then removed from the working area by exhausting the exhaust air

Electrolyte Resistance

An important component in every battery is the electrolyte, which ensures the transport of ions between the electrodes. The complex system of solvent, conductive salt and additives can attack components that come into contact with it. Schmalz offers suction cups made of materials resistant to corrosion by electrolytes. Compared with suction cups made of other materials, it can be used for a long time, to improve the productivity and output of the line.
