Filling of battery cells with electrolytes
Filling electrolytes into battery cells is a critical step in battery manufacturing. Factors such as electrolyte formulation, pressure and temperature must be considered in the filling process.
Critical to battery performance and life are the quality of the electrolyte and the accuracy of the filling process. Small dispensing errors cause large variations in performance. High-precision micro annular gear pumps ensure this necessary precision.
Lithium-based liquid battery electrolytes are crystallizing and hazardous to health, and require the use of hermetic pumps. In this application, the magnetic hermetic pump mzr-7265 doses volumes between 4 - 8 ml in 2 s with a deviation of less than 1%. The process takes place under vacuum conditions.
Decision criteria for these pumps
- precise, low pulsation dosing
- delivery of crystallizing liquids
- short cycle time
