Film 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.

Products
  • c2_img2.jpg
    Ceramic + PVDF Coating

    This product is coated with ceramic as first layer and then PVDF coating as second layer of the polyolefin separator, thus to realize the tight bonding between the separator and the positive and negative electrodes of the cell, reduce the deformation of the cell, and improve the reaction interface.

    Fluoropolymer Coating

    This product is a fluorine-free polymer coating on the surface of the polyolefin separator, so that the separator and the positive and negative electrodes of the cell are tightly bonded, the deformation of the cell is reduced, and the reaction interface is improved. 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 Hybrid Coated Separator

    This product is a ceramic and PVDF hybrid coating on the surface of the polyolefin separator to improve the adhesion between the separator and the positive and negative electrodes of the cell, to reduce the deformation of the cell, improve the reaction interface, and to improve the wettability of the electrolyte.

    Ultra-Thin Ceramic Coated Separator (UCCS)

    The product obtains a 0.5μm ultra-thin coating by coating the surface of the polyolefin separator with inorganic nano-ceramics, which effectively reduces the thickness of the ceramic coating and maintains the high temperature resistance of 150 °C. On the premise of ensuring the safety performance of lithium-ion batteries, it improves its energy density.
