FT-551Series of automatic lithium battery pole piecesresistancetester
Functional Description：
Using a flat probe to analyze the overall resistance of the electrode piece by applying pressure to the tested sample, automatic pressure is applied, and the pressure can be set; PCSoftware interface operation,Under multiple measurement modesRealize pressure and resistance,Relationship diagram between resistivity and conductivity; Provide data and report generation management.Automatic real-time collection of sample thickness data and environmental temperature and humidity.
Reference method description:
1.Using a two probe method to directly measure the overall resistivity of the polarizer, including the resistance of the probe itself, the contact resistance between the probe and the coating, the resistance of the coating, the contact resistance between the coating and the current collector, and the resistance of the current collector itself; Solve the problem that the four probe method test data cannot describe the overall battery electrode value;
2.The testing process is basically the same as the actual battery application, and a total test value includes the electronic conductivity characteristics of each part, studying the influence of the process on the electrode resistivity.
3.For those with high resistanceLFPPolar electrodes can obtain stable results when the loading current is relatively low, while for low resistance graphite electrodes, stable results can only be obtained when the loading current is relatively highLFPTheNMCGraphite electrode, loaded with current10mAThe above can provide relatively stable measurement results. As the loading pressure increases, the resistivity of the graphite electrode decreases.
4. The factors affecting the conductivity of polarizer include the content and distribution of conductive agent, dry powder mixing intensity, compaction density, and the bonding state between current collector and coating
