This is a market dataset, representing the consumption market of the region. The dataset includes transport from the gate to the point of consumption, and transport services are calculated based on the transport situation of this product in the region. The polyethylene battery separator is a membrane that separates the positive and negative electrodes; if you cannot specify the composition of the battery separator, you can use this dataset, which is a weighted average of the datasets: \"battery separator, polyethylene\" and \"battery separator, polypropylene\". For specific technical details, scope boundary, etc., refer to various battery separator production datasets. The infrastructure such as manufacturing equipment and facility construction used in production is not included within the dataset boundary. The production process of battery separator includes material input, casting, longitudinal stretching, transverse stretching, extraction, fixing, slitting, etc.
