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.
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.
Most of the researchers are focusing on the separator research of lithium-ion batteries. Although there have been some research reports on the separators of secondary batteries such as sodium ion batteries and potassium ion batteries, they are still insignificant compared with their research reports on electrode materials.
This review summarizes and discusses the five types of separators used in rechargeable batteries, namely microporous membranes, non-woven membranes, composite membranes, modified polymer membranes, and solid electrolyte membranes. In general, lithium-ion battery separators are currently a research hotspot in battery separator research.
At present, the separators are developed from various types of materials such as cotton, nylon, polyesters, glass, ceramic, polyvinyl chloride, tetrafluoroethylene, rubber, asbestos, etc... In conditions like rising in temperature, the pores of the separator get closed by the melting process and the battery shuts down.
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.
