Contamination in Battery Manufacture

Shelia Hamilton

Contamination, both ionic and particulate, is a major issue in R2R manufacture of Li-Ion Batteries. European Union funded research has shown that there are many opportunities both within the manufacturing process itself and within the supply chain for contamination to be introduced into the process. This paper will outline the areas within the process which are sensitive to both types of contamination, highlighting the defects the contamination can cause, with special focus on safety critical defects. The paper will conclude by discussing the steps which can be taken to reduce contamination throughout the process resulting in higher yields.
