03FILM MATERIALS
AND FILM COATING
Using advantages acquired by building the integrated layout of Separator, base film, coating and slurry, PTL's Separator Materials and Coating Division has developed a new process of Separator high-speed line and online coating, broke into the international market and expanded the second business growth point.
Relying on the new aluminum-plastic film factory in Jiangsu, PTL actively entered the high-end CE and EV pouch cell market, and accelerated the process of localization and substitution.
Film Packaging Material
Features
Aluminum-plastic packaging film is a packaging material for pouch lithium-ion batteries. It is composed of multi-layer plastic, aluminum foil and adhesive, so it has good plastic shape, hot-pressing sealing, and good isolation. It is suitable as packaging materials for lithium-ion battery cells.

Product
Ceramic+PVDF coating
Product Features
This product first coats the ceramic on the surface of the polyolefin separator and then coats the PVDF coating, so as to realize the tight bonding between the separator and the positive and negative electrodes of the battery cell, reduce the deformation of the battery cell, and improve the reaction interface
Fluoropolymer Coating
Product Features
This product is coated with a fluorine-free polymer coating on the surface of the polyolefin separator, so as to realize the tight adhesion between the separator and the positive and negative electrodes of the battery, reduce the deformation of the battery, and improve the reaction interface. The overall thickness is reduced from the traditional 1μm coating to 0.5μm, which is suitable for high energy density projects of lithium-ion batteries
Ceramic+PVDF Mixed Coating Diaphragm
Product Features
This product is coated with a ceramic and PVDF mixed coating on the surface of the polyolefin separator to improve the bonding performance between the separator and the positive and negative electrodes of the battery, reduce the deformation of the battery, improve the reaction interface, and improve the wettability of the electrolyte
Ultra-Thin Ceramic Coated Separators (UCCS)
Product Features
The product obtains 0.5μm ultra-thin coating by coating inorganic nano-ceramics on the surface of polyolefin separator, effectively reduces the thickness of ceramic coating, and maintains high temperature resistance performance at 150°C, and improves the energy density of lithium-ion batteries on the premise of ensuring the safety performance of lithium-ion batteries
Solventborne Coated Separators (OBS)
Product Features
This product is coated with solvent-based method to obtain oily PVDF coating, which has high adhesion performance of pole piece and fast lithium ion passing performance, so that lithium ion battery can obtain fast charging performance
