A novel low-cost lithium-ion battery separator production process pe

The present invention discloses a process for the production of low-cost lithium-ion battery separator PE belongs to the field of battery separators. Its production process comprising: a first polyethylene and the organic solvent were uniformly mixed to obtain a mixture; extruding the mixture, respectively, the measurement, the cast piece obtained oily film, and then an oil film after biaxial stretching into a vacuum oven set given temperature and negative pressure volatilize the organic solvent in the oil film to obtain a porous membrane dried raw product, after cooling the organic solvent is volatilized into the exhaust adsorption apparatus, selection of the adsorbent for adsorbing an organic solvent, adsorption has been parsed, the exhaust gas after desorption condensed into the stratification tank, separated from the organic solvent into the recycling system ingredients. This method avoids the traditional wet process extraction solvent extraction and separation of the mixture, and the exhaust gas recovered solvent system can continue to the batching system recycling, greatly reducing the production cost.
