White separators don’t contain harmful substances such as organic solvent and don’t cause self-discharge and abnormal internal corrosion.
They don’t contain oily ingredients that make inside the batteries dirty while using them, either, so transparent battery cases don’t get dirty and become black because of separators.
We don’t use harmful substances (ex: volatility organic compounds like VOC) for products or even during the manufacturing process, so you can use them without anxiety under any environmental regulation in the future.
