Moisture Matters: Accurate Water Determination in Battery Materials

Water impacts battery materials at various levels, ranging from the molecular structure to overall performance. It can react with salts, causing corrosion and short circuiting and, ultimately, a reduction in battery life.

Karl Fischer titration, known for its accuracy in measuring trace amounts of water, is an ideal method for monitoring water content in various battery components. This includes not only cathode and anode raw materials, but also electrolytes and separators used in the battery manufacturing process.

During this webinar, Dr. Roman Neufeld, Sr. Research Scientist from Honeywell, will discuss recommended coulometric KF reagents for battery electrolytes with and without reactive additives. Eduardo Simões, Product Specialist at Metrohm USA, will discuss how to analyze battery materials using Karl Fischer titration and provide an overview of other titration battery applications.

Key Learning Objectives:

• Learn how to analyze battery liquid samples for moisture and avoid side reactions with special KF reagents.

• Understand how the KF Oven technique works for solid materials and for liquid samples that cause side reactions with direct inject.

• Learn about the main potentiometric titration applications for battery materials such as lithium salts, HF, and pure metals like Ni/Co/Mn.

Who Should Attend:

• QC analysts performing KF titration on battery raw materials, electrolytes, and separators.

• R&D scientists searching for improvements on their research projects.

• Anyone from the battery market wanting to learn about how important this analysis is for their materials and products.
