Abstract
A device and a method for drying a battery separator membrane. The method is mainly by adding a drying device to provide a drying process prior to the lamination in the battery automated manufacturing process, so that in the process of sequentially, stacking the positive, negative electrode plates and the separator membrane in an interval into a battery cell, the drying device is used to continuously dry the separator membrane in advance to ensure that the moisture content of the separator membrane itself is effectively removed. The drying device mainly includes a closed space, and a plurality of sets of rollers at a certain distance from each other is arranged arbitrarily to make the long strip-shaped separator membrane wind around all the rollers to get a fully unfolded state. This couples with the introduction of continuous circulating wind into the closed space to blow the separator membrane to achieve the desired drying effect.
