1. Background of the program.
With the rapid development of the electric vehicle industry, the performance and safety of secondary lithium-ion batteries as their core power source have become particularly important. As an important component of the battery, the purity of the electrolyte has a direct impact on the performance and safety of the battery. Therefore, the accurate detection of tiny particles in the electrolyte has become a key part of battery quality control. As an advanced detection equipment, the liquid particle counter can quickly and accurately detect the number and size distribution of particles in the electrolyte, which is of great significance for ensuring the quality and performance of the battery.
II. Programme Objectives.
The purpose of this program is to establish a complete electrolyte particle counting and detection system for secondary lithium-ion batteries, and to accurately detect the number and particle size distribution in the electrolyte by using a liquid particle counter to ensure the excellent performance and safety of the battery. At the same time, this solution will also provide reliable data support for quality control in the battery production process.
3. Instruments and reagents.
1.Instrument: Liquid particle counter.
2.Reagent: Secondary lithium-ion battery electrolyte.
Fourth, the detection steps.
1.Prepare the sample: Remove the appropriate amount of electrolyte sample from the battery.
2.Dilution of the sample: The electrolyte sample is appropriately diluted according to the requirements of the instrument.
3.Detection: Particle count detection of diluted samples using a liquid particle counter.
4.Data processing: collation, analysis, and interpretation of inspection data.
5. Interpretation and judgment of results.
Based on the test data, the number and size distribution of particles in the electrolyte can be obtained. The quality of the electrolyte is judged according to the set quality standards. If the test results do not meet the standards, further investigation of the cause and appropriate measures are required to ensure the quality and performance of the battery.
6. Precautions.
1.Ensure the accuracy of the instrument: The instrument should be calibrated before use to ensure the accuracy of the test results.
2.Avoid cross-contamination: During sampling and dilution, the purity of the sample should be ensured to avoid the impact of cross-contamination on the test results.
