NMP Solvent Recovery in Lithium Ion Battery Production

Lithium-ion batteries play a crucial role in today’s society; from cell phones to electric vehicles, they have become common place in the modern world. However, their production—particularly the fabrication of the electrodes—is a costly, technically challenging, and potentially dangerous process. Are you doing everything possible to ensure that your operation is not only safe, but running at peak efficiency?

NMP is a solvent used during the manufacture of cathode electrodes. The solvent is recovered during a drying phase. If not properly addressed, the moisture in the dryer air can accumulate in the NMP overtime as the solvent is recovered. The presence of moisture in the NMP can lead to quality issues in the final product. We have an excellent write-up here on our webpage that discusses this in more detail if you would like to learn more. More importantly, NMP is also a volatile compound that can explode if levels are above its lower explosive limit. Ensuring that dryers remain below this limit is crucial to keeping any manufacturing plant safe.

Applied Analytics can help you avoid these issues by alerting you to these changes in real time. Our analyzers can monitor the moisture level of distilled NMP to ensure moisture is below acceptable limits. Our analyzers can also ensure that NMP vapor remains well below explosive limits. Don’t leave your process up to chance, reach out to Applied Analytics to learn more about how our analyzers can not only keep your process safer but also make it more efficient.
