The Significance of Slurry Resistivity
The slurry is an important intermediate product in the production of lithium-ion batteries. The uniformity and stability of the slurry greatly affect the consistency and electrochemical performance of the final battery cell. The current method of monitoring slurry only has viscosity parameters, which cannot accurately evalu- ate the uniformity and stability of its electrical proper- ties. However, the slurry conductivity parameters and slurry formulation, conductive agent type and content,
binder type andcontent etc, which all have significant correlation to monitor the production of slurry, and the slurry may have gel sedimentation after dwelling for a period of time after mixing. At this time, the conductivity value will also show varying degrees of change. Therefore, the conductivity of the slurry can be used as a method to characterize the uniformity and stability of the electrical properties of the slurry.
Monitoring the conductivity of the slurry, on the one hand, it can evaluate the influence of different active materials, conductive agents, binders, solid content, etc. on the electrochemical perfor- mance, for material evaluation and screening, on the other hand, it can also be used for process stability monitoring, which can quickly identify abnormalities in the mixing process, and avoid the waste of time and cost caused by defective products flowing into the subsequent process.
Slurry Resistivity Test Principle
Test steps: Putting a certain volume of slurry (~80mL) into the measuring glass, inserting a clean electrode pen, start the software, start to test the changes in the slurry resistivity at the three pairs of electrodes over time and save it in the file.
Test parameters: Resistivity, Temperature, Time
Calculation formula: Resistivity (Ω*cm):ρe=U/I*S/l
Character:
1. Separate the voltage and current lines, eliminate the influence of inductance on voltage measurement, and improve the accuracy of resistivity detection;
2. The disk electrode with a diameter of 10mm ensures a relatively large contact area with the sample and reduces the test error;
3. Real-time monitoring of changes in resistivity of the slurry at three positions in the vertical direction over time;
