AOT-BSR2300 Three Electrode Battery Slurry Resistivity Tester
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
Test program: Three operators, five parallelsamples, and random testing.
Test method: Sonicating the electrode pen withdeionized water for 30 seconds,and drying it with the dust-freepaper. Then five parallel sampleswas tested, and the fifth set of datawas taken for the GRR analysis.

FAQ
Q1: How to ensure the consistency of measurement of three pairs of electrodes?
A: Each pair of electrodes is calibrated by standard solution (10Ω-cm) before delivery, and the deviation of parallel testing is <0.3%. It is recommended to recheck with standard solution every month and perform automatic compensation by software.
Q2: What is the frequency and duration of ultrasonic cleaning of electrodes?
A: After each test, the electrode should be ultrasonically cleaned with deionized water for 30 seconds. If the slurry contains high binder (e.g. CMC), it can be extended to 60 seconds to prevent the electrode surface from residue affecting the accuracy.
Q3: Does it support non-aqueous slurry testing?
A: Compatible with aqueous and NMP-based pastes, the electrode should be thoroughly cleaned and dried after testing to avoid solvent corrosion of the electrode coating.
Q4: How to handle the data of five parallel tests?
A: The software automatically eliminates outliers (±3σ criterion) and takes the last three valid data to generate a GRR report, which can be exported to CSV format for SPC analysis.
Q5: Can the battery slurry resistivity tester be connected to a LIMS system?
A: RS232 interface is standard, and TCP/IP protocol can be customized to realize automatic uploading of test data to the laboratory information management system.
