The polyethylene battery separator is a membrane that keeps the positive and negative electrodes separated; if you cannot specify the exact composition of the battery separator, this dataset can be used. This dataset is a weighted average of the following: \"Battery separator, polyethylene\" and \"Battery separator, polypropylene\" datasets. Descriptions of technical details, scope boundaries, etc., can be found in various battery separator production datasets. Infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundaries. The production process for Battery separator includes material feeding, casting, longitudinal stretching, transverse stretching, extraction, setting, slitting, and other process steps.
