Determination of Organic Impurities (TOC) In Raw Materials for Cathode Production in Lithium-Ion

Challenge: The high-temperature determination of low TOC concentrations in high-salt matrices places high demands on the analytical system used regarding its detection strength and matrix tolerance.

Solution: The high-temperature TOC analyzer multi N/C 3100 allows the routine analysis of lowest TOC concentrations in high salt samples

Intended audience: Manufacturers of raw materials (salts) for cathode materials for LIB, cathode manufacturers, LIB manufacturers, battery recycling companies

Lithium-ion batteries (LIB) consist of a cathode, an anode, a separator, the electrolyte and finally the cell housing. The main cost factor in the production of battery cells are the raw materials used. The cathode material is usually the most expensive component of the entire battery. For cathode production, active material, which is used to store the lithium ions, is applied to aluminum foil. The composition of the active material can vary and is the subject of current cathode research to make LIB even more powerful and energy rich.
