Battery Isolation

Battery isolation is the process of separating one battery or power source from another to prevent unwanted current flow. This is important in systems that use multiple batteries or power sources, such as boats, RVs, and off-grid homes. Without proper isolation, current can flow between batteries or power sources, which can cause damage or even create safety

The safety and efficiency of separator film can be improved by coating it with materials such as ceramic.

Why should a battery separator film be thin?

Thin-gauges and uniform thickness: Battery separator film (BSF) must be thin to facilitate the battery's energy and power densities. To support many charging cycles, its thickness must be uniform. Optimum porosity enables the electrolyte to be thoroughly moistened and ensures facile ionic conduction.

How does a battery separator work?

The separator blocks the flow of electrons inside the battery.” The uniform coating of the anode and cathode materials, the use of high quality separator film and accurate thickness measurement of the calendered electrode are critical to the performance and safety of the battery.

How to manufacture microporous separators for Li-ion batteries?

For large-scale commercial production of microporous separators for Li-ion batteries there are two basic manufacturing processes. The so called wet process (with up to 70% oil) and dry process, both covered and distributed by Coperion.

What is separator film made of?

“Separator film can be made of different materials and can be produced in different processes. The most common processes are the dry and the wet process, and the most common raw materials are polypropylene and polyethylene”, Alexander Bruckmüller, Product Manager Cast Film Extrusion of SML, explains.

Which process is used to make separator film?

On SML’s cast film lines, separator film is manufactured using the dry process. Compared to the wet production method, the dry process has significant advantages: Lower material costs: In the dry process, rather standard PP or HDPE resins are used.
