Abstract
Battery separator comprising a consolidated nonwoven mat of ultrafine polymeric fibers in which at least 10% of said fibers have a diameter less than 1 micron and which mat has an average pore size of less than 3 .mu.m. The fiber mat is formed by meltblowing using modified conditions to produce a self-bonded web having the desired content of ultra fine fibers.
