Abstract: The present paper focus on identifying the optimal microstructure of a non conducting polyolefin separator material have been investigated by Scanning Electron Microscope (SEM) technique. In this study, experiments are conducted by varying the surface coating time from one minute to eight minutes and also varied the accelerated voltage from one to ten kilo volt in order to identify the optima conditions for desired microstructural separator material for lithium ion battery applications. From the studies, it was observed that the coating time on the specimen from three to five minutes and accelerating voltage applied from five kilo volt to ten kilo volt was found to be preferred conditions for obtaining the desired microstructure of polyolefin based separator material. The observed SEM results are presented and discussed.
