The substrate material used in lithium -ion battery diaphragm is polyolefin, and polyolefins have excellent mechanical properties, chemical stability and relatively cheap characteristics. The diaphragm material mainly includes polypropylene, polyethylene materials and additives. The substrate material is directly related to the mechanical properties of the diaphragm and the infiltration of the electrolyte. Although in recent years, there have been studies for lithium -ion battery diaphragms such as polytin fluoride, cellulose composite membrane and other materials, so far the commercialized battery diaphragm materials are still mainly used in polyethylene and polypropylene microres. The technology of lithium -ion battery diaphragm is mainly wet and dry method. The dry method has two types of one -way stretching technology and two -way stretching process.
1. The wet process of lithium -ion battery diaphragm production is also known as phase separation method or armal phase separation method. The high -boiling small molecules are added as a pores into a polyolefin, which is heated and melted into a uniform system. Separate, use organic solvents to extract small molecules after stretching, and can prepare mutually interactive microne membrane materials.
The representative companies that adopt the law include Japan Asaka, Dongfan, and ENTEK in the United States. It is currently mainly used for single -layer PE diaphragm. Although the pore rate and permeability are controlled, the wet process needs to consume a large amount of organic solvents. On the one hand, it is necessary to consider the recycling and utilization of solvents.
2. The two -way stretching process of lithium -ion battery -proofing method of the production of lithium -ion battery separation is a process developed by the Institute of Chemistry of the Chinese Academy of Sciences in the early 1990s. By adding nuclear effects to polypropylene.
The β crystal improvement agent, using the differences between the density between different phase of polypropylene, a crystal transformation occurred during the stretching process to form micropores.
3. The one -way stretching process of lithium -ion battery separation film production is the one -way stretching process of the one -way stretching process. It is a method of producing high -end crystal to polypropylene or polyethylene film through the method of producing hard elastic fibers. Giver -crystal -oriented orientation thin film. This thin film first stretches at low temperature to form micro -defects, and then the defect is opened at high temperature to form micropores.
