Driven by the rapid growth of the new energy vehicle market, the new energy power battery industry is also developing rapidly.
The four main components of new energy batteries: positive electrode material, negative electrode material, separator, and electrolyte.
What I want to introduce to you today is the lithium electronic battery separator.
There are a variety of batteries in people’s lives, such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, thermal batteries and fuel cells.
The battery is composed of positive and negative electrodes, battery separator and electrolyte.
The battery separator is an important part of the battery. It refers to a layer of separator material between the positive and negative electrodes of the battery. Its main function is to insulate electrons and conduct ions; that is, to prevent the positive and negative electrodes in the battery from The electrons between them are in direct contact, but the ions can pass freely.
The lithium electronic battery separator is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the lightest varieties of all plastics currently.
It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.
The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The surface of the product is glossy.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the R&D, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, lithium electronic battery separators, Teflon films and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
