| titleOfInvention | Power lithium ion battery and composite diaphragm thereof |
| abstract | The invention discloses a composite diaphragm of a power lithium ion battery. The composite diaphragm comprises a supporting layer and an inorganic coating layer, and is characterized by further comprising a polytetrafluoroethylene layer, wherein the inorganic coating layer is coated on the supporting layer, the polytetrafluoroethylene layer is coated on the inorganic coating layer, and the surface and interior of the inorganic coating layer have porous interconnection structures. According to the composite diaphragm of the power lithium ion battery, organic/inorganic composite films are compounded with a polytetrafluoroethylene microporous film, and due to the existence of the polytetrafluoroethylene microporous film, in the process of manufacturing the composite diaphragm of the power lithium ion battery and in the process of manufacturing a wound electrode group of the battery, the inorganic coating layer has good adhesive property on the composite diaphragm and is difficult to fall off; and the composite diaphragm has the advantages of high tearing strength, perforation resistant strength, high-temperature and low temperature resistance, high corrosion resistance, electrical insulating property and chemical stability, and particularly the high oxidation-reduction resistance of polytetrafluoroethylene has more superiority for prolonging the service life of the lithium ion battery and improving the use safety of the lithium ion battery. |
