Briefly describe the dry and wet production processes of Nickel Hydride Batteries separators
Dry process of iron-lithium ion battery separators
The dry process can be divided into uniaxial stretching process and biaxial stretching process. The dry uniaxial stretching process is a method of producing hard elastic fibers to prepare a low-crystallinity, highly oriented polypropylene or polyethylene film, and obtain a high-crystallinity film during high-temperature annealing. This film is first stretched at low temperature to form micro defects, and then the defects are pulled apart at high temperature to form micropores.
The dry biaxial stretching process, by adding a β crystal modifier with nucleation function to polypropylene, utilizes the density difference between different phases of polypropylene, and transforms polypropylene from a crystal form to form micropores during the stretching process. At present, more than one-third of my country's production uses the dry biaxial stretching process, and the products occupy a large proportion in the low- and medium-end markets. Application range: large lithium-ion power lithium batteries (electric vehicles, electric motorcycles, power tools, large energy storage equipment, special large batteries)
Wet production process of iron lithium ion battery separator
Wet production process, also known as phase separation method or thermal phase separation method, is a process in which liquid hydrocarbons or some small molecular substances are mixed with polyolefin resins, heated and melted to form a uniform mixture, then cooled for phase separation, pressed to obtain a membrane, and then heated to a temperature close to the melting point, biaxially stretched to orient the molecular chains, and finally kept warm for a period of time, and the residual solvent is washed away with volatile substances to prepare microporous membrane materials that are interconnected.
The wet production process can not only prepare microporous membrane materials that are interconnected, but also produce power iron lithium ion battery separators with high longitudinal and transverse strength. At present, the wet production process is mainly used to produce single-layer lithium ion battery separators. Application range: high-performance lithium ion batteries, etc.
In terms of physical properties and mechanical properties, the separators produced by the dry uniaxial stretching process have more advantages. However, the lithium-ion battery separator produced by the wet production process has a high porosity and good air permeability, which can meet the requirements of high current charging and discharging of power lithium batteries.
