This episode delves into the critical role of regulatory compliance and advanced analytical methods during chemical processing in the lithium-ion battery industry. Experts explore how manufacturers navigate regulations such as the Restriction of Hazardous Substances (RoHS), which limit the use of toxic metals, and how accurate documentation and battery passports can support traceability and future compliance. The discussion emphasizes the importance of verifying chemical composition and monitoring impurities to maintain product quality, safety, and environmental standards.

The episode also highlights best practices for method development and optimization using ICP-OES to simultaneously quantify major components and trace-level elemental impurities. Speakers share strategies such as sample dilution, matrix-matched calibration standards, multi-line spectral selection, background correction, and the use of internal standards to address interferences. ICP-MS and alternative elemental analysis techniques are also discussed to ensure accurate trace analysis and cross-validation of results.

Key takeaways include:

• Navigating regulatory compliance with RoHS and other hazardous material restrictions.
• Documenting chemical usage and material fingerprints for battery passports and traceability.
• Optimizing ICP-OES and ICP-MS methods for simultaneous analysis of major and trace elements.
• Implementing background correction, matrix matching, and spectral line selection for precise measurements.
• Leveraging multiple analytical methods or reference materials to ensure accuracy and reliability.
