Customer ServiceSimultaneously, the separator allows the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell. To fulfill these functions, separator film in lithium-ion batteries must meet a number of requirements:
1. Polypropylene film for electrical and thermal insulation of batteries and accumulators Polypropylene has excellent dielectric properties, excellent impermeability, and is easily deformed. Formex is the first choice for engineers and designers. It is very durable and has excellent dielectric strength.
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.
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.
