Multi-layer composite film for an inner sealant layer of a pouch-type lithium secondary battery |
| abstract |
The present invention is a core layer in which two-dimensional plate-shaped inorganic particles are mixed with a polypropylene resin copolymerized with maleic anhydride; And a skin layer of a polypropylene resin formed on both sides of the core layer. It relates to a multilayer composite film for an inner sealant layer of a pouch-type lithium secondary battery. The multilayer composite film for the inner sealant layer of the pouch-type lithium secondary battery containing the two-dimensional plate-shaped inorganic particles according to the present invention has excellent moisture permeability compared to the conventional single-layered inner sealant layer, so the fluorine-containing electrolyte solution of a lithium secondary battery Corrosion and destruction of the entire cell can be prevented by suppressing the generation of hydrofluoric acid generated by the reaction of moisture and water, and since it has chemical resistance and heat resistance, it can be commercialized as a material for the inner sealant layer of a pouch-type lithium secondary battery. |
