Abstract

Separator is one of the key components of primary batteries and affects the safety and life of the battery. In this study, separator was prepared based on the polyamide (PA) nonwoven with PA nanofiber. PA nonwoven was prepared meltblown method. The spinning conditions for meltblown were optimized to improve the mechanical strength and the electrolyte property, which play an important roll to determine the electrical performance of battery. It was revealed that the PA nanofiber in the PA separator contributed to the electrolyte absorption and electrolyte absorption speed as well. The electrical performance of battery having PA separator was also investigated.
