According to data research and statistics, it is found that under the background of relatively stable consumer lithium battery market, the development of the global new energy vehicle industry will still be an important driving force for the growth of demand for lithium electronic battery separators.
From an academic point of view, the separator is inert in the battery, that is, the separator is not a necessary component of the battery, but is only a requirement for the industrial production of the battery.
The existence of the separator must first ensure that it cannot deteriorate the electrochemical performance of the battery, which is mainly reflected in the internal resistance.
The ratio between the resistivity of the separator containing the electrolyte and the resistivity of the electrolyte itself is called the MacMullin number.
Generally speaking, the value of consumable lithium-ion batteries is close to 8. Of course, the smaller the value, the better.
The products of lithium electronic battery separator manufacturers are microporous membranes made of polymer compounds polymerized from polytetrafluoroethylene using special processes such as calendering, extrusion, and biaxial stretching.
The film also has excellent corrosion resistance, aging resistance and high temperature resistance, and the operating temperature can reach -150℃-250℃.
It has been widely used in many fields such as electronics, chemical industry, medicine, military, aerospace, clothing, environmental protection and so on.
The lithium electronic battery separator produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely fine particles with a diameter of 0.1um-0.3um, The filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
