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.
What makes a good battery separator?
On top of that, separators also need to be robust enough to withstand high tension during the battery manufacturing process. Pore size also matters - an ideal battery separator’s pores should be smaller than the ion size of electrode materials, including electrode active materials, conductive additives, etc.
Why should a battery separator be placed between two electrodes?
Positioning the separator between the two electrodes is essential because it helps prevent the battery from electrical short-circuiting during electrolysis and limiting excessive current. A good battery separator is well balanced between porosity (ability to transport) and mechanical robustness.
Which electrode materials should be used for a battery separator membrane?
The development of separator membranes for most promising electrode materials for future battery technology such as high-capacity cathodes (NMC, NCA, and sulfur) and high-capacity anodes such as silicon, germanium, and tin is of paramount importance.
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.
How do you choose a battery separator?
A porous membrane placed between electrodes of opposite polarity, permeable to ionic flow but preventing electric contact of the electrodes. The considerations that are important and influence the selection of the separator include the following: In most batteries, the separators are either made of nonwoven fabrics or microporous polymeric films.
