PAT-Core: Lower Plunger Configurator

Use our configurator to determine the proper lower plunger for your battery test.

By default, the lower plunger serves as the positive current collector . The choice of materials is the same as for the upper plunger, however, the lower plunger comes in different sizes (height numbers) to account for different thicknesses of the lower electrode and the separator. Available height numbers range between 50 and 800 in steps of 50. The proper plunger height must be chosen to ensure that the pre -assembled separator is not excessively bent during assembly of the PAT -Core. The proper height number depends on both the thickness of the lower electrode and the thickness of the built -in separator. Please note that the height number starts with a zero point offset of 50. The height number does not refer directly to the height of the lower electrode in μm.

> Watch our explanation video here.

Good case: No bending of built-in separator; reference ring is in plane with separator.

 

Gap too large: Excessive downward bending of built-in separator; reference ring is out of plane with separator. -> Lower plunger height must be increased.

 

Gap too small: Excessive upward bending of built-in separator; reference ring is out of plane with separator. -> Lower plunger height must be reduced.
