Use our configurator to determine the proper lower plunger for your battery test.
PAT-Core: Lower Plunger Configurator
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 μm. 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 does not refer directly to the height of the lower electrode in μm.
