6 FAQs about [Flow battery separator production]

What is a battery separator?

A separator is a permeable membrane placed between a battery's anode and cathode. The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.

Can a porous separator be used for flow batteries?

The use of porous separators for flow batteries has already been put forward by the National Aeronautics and Space Administration (NASA) in the 1970s: “A further method to produce highly selective low resistance membranes is to use a porous plastic film as the substrate for a thin layer of ion exchange resin.

What is a battery separator film line?

Solutions > Lines for Production of Battery Separator Film Lines A separator in a lithium-ion battery is a crucial component that separates the positive and negative electrodes, preventing short circuits and ensuring safe and efficient operation of the battery.

Why is a battery separator important?

The main purpose of the separator is to prevent electrical and physical contact between the electrodes while its porous structure allows an electrolyte (typically liquid) to transport ions. Conventionally, the separator is therefore a passive component. Despite this, it plays a vital role in the safety and performance of the battery.

What is a liquid electrolyte battery separator?

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.

Why is a lithium-ion battery separator important?

As a vital part of lithium-ion batteries (LIBs), the separator is closely related to the safety and electrochemical performance of LIBs.
