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.
For example, consider a three-layered separator with a PE battery separator material sandwiched between two layers of Polypropylene - PP Separator. The PE layer will melt at a temperature of 130°C and close the pores in the separator to stop the current flow; the PP layer will remain solid as its melting temperature is 155°C.
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.
The major role of the battery separator is to physically isolate the anode from the cathode while allowing mobile Li-ions to transport back and forth . Unfortunately, two technical challenges associated with separator puncture and significant thermal shrinkage of polymer separators threaten the overall safety of batteries.
In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active. Many efforts have been devoted to developing new types of battery separators by tailoring the separator chemistry.
Battery isolators and separators are different in that a battery isolator is one-directional and prevents battery over-discharge. On the other hand, the separator is multi-directional and serves several purposes, including checking the battery's voltage, preventing short-circuiting, and preventing battery over-discharge.

What is Separated Extra Low Voltage (SELV) Separated Extra Low Voltage (SELV) system is an extra low voltage electrical circuit that is electrically separated from other circuits that carry higher voltages, isolated from the earth and from the protective earth conductors of other circuits.
Lithium-ion Battery. A lithium-ion battery, also known as the Li-ion battery, is a type of secondary (rechargeable) battery composed of cells in which lithium ions move from the anode through an electrolyte to the cathode during discharge and back when charging.. The cathode is made of a composite material (an intercalated lithium compound) and defines the name of the Li-ion …
A battery is a device that stores energy and then discharges it by converting chemical energy into electricity.Typical batteries most often produce electricity by chemical means through the use of one or more electrochemical cells.
