This episode highlights complexities of elemental analysis during lithium-ion battery component manufacturing, with a focus on lithium salts, graphite, silicon-carbon composites, and lithium metal oxides. Experts highlight the importance of precise control over material composition to ensure battery performance, safety, and longevity. The discussion emphasizes critical impurities, analytical methodologies, and process optimizations that improve both efficiency and sustainability in component manufacturing.

Panelists explore the major challenges of lithium salt analysis, including the hygroscopic nature of lithium hydroxide and the difficulty of fully digesting complex materials. Various sample preparation techniques, such as microwave digestion, fusion followed by acid digestion, and direct solid analysis using laser ablation or graphite furnace methods, are examined. The conversation also highlights the role of specialized equipment, like wide-bore V-groove nebulizers for ICP-OES, in achieving accurate and stable results without the need for additional filtration or complex digestion steps.

Key takeaways from this episode include:

• Managing lithium salt hygroscopicity and other material handling challenges.
• Best practices for sample preparation and digestion of graphite, silicon-carbon composites, and lithium metal oxides.
• Using alternative analysis methods like laser ablation and graphite furnace ICP-OES to avoid digestion pitfalls.
• Ensuring accuracy through method validation, spike recovery, and reference material checks.
• Leveraging advanced ICP-OES equipment to simplify workflows and achieve reliable elemental quantification.
