The separator material is non-conductive, the type of battery is different, and the separator used is different. For a lithium ion battery, since the electrolyte is an organic solvent system, the separator is required to have the following properties.
In the lithium battery series, since the electrolytic solution is an organic solvent system, a separator material resistant to an organic solvent is required, and a polyolefin porous film having a high strength thin film is generally used. 1. it has electronic insulation to ensure the mechanical isolation of the positive and negative electrodes.
Separators are critical components in liquid electrolyte batteries. A separator generally consists of a polymeric membrane forming a microporous layer. It must be chemically and electrochemically stable with regard to the electrolyte and electrode materials and mechanically strong enough to withstand the high tension during battery construction.
Polyolefin materials have excellent mechanical properties, chemical stability and relatively inexpensive characteristics. Therefore, polyolefin microporous membranes such as polyethylene and polypropylene have been used as lithium battery separators in the early stage of research and development of lithium batteries.
These separators are typically made from polyethylene (PE) or polypropylene (PP). Polymeric separators offer excellent dielectric properties, thermal stability, and mechanical strength. They can be manufactured with different pore sizes and thicknesses to meet the specific requirements of different battery applications.
Early separators were made of rubber, glass fiber mat, cellulose and polyethylene plastic. Wood was the original choice but it deteriorated in the electrolyte. Nickel-based batteries use separators of porous polyolefin films, nylon or cellophane.
