Contamination in R2R Battery Manufacture

Contamination in R2R Battery Manufacture

Contamination, both ionic and particulate, is a major issue in the R2R manufacture of Lithium Ion batteries. 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 particulate contamination, highlighting the defects which 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.
