For separator types used in North America and Western Europe the trend is towards microporous polyethylene (PE) materials. Battery industries in these regions have demonstrated the superiority of PE separators with respect to other types in terms of physical, electrical and chemical properties. Grace battery separator technical center (BSTC) in Hamburg (Germany) has analysed 53 failed batteries removed from field service and found only 11.3% of failures are related to PE separators. In explicit terms, separator-related failures are due to deep-discharge and subsequent charge of the batteries
