Since the electrolyte is an organic solvent system for lithium-ion batteries, the separator should generally possess the following properties: The pore size and structure are usually influenced by polymer compensation and stretching conditions. The pore size affects the transit of the anode and cathode of the li-ion battery.
Separators in Lithium-ion (Li-ion) batteries literally separate the anode and cathode to prevent a short circuit. Modern separator technology also contributes to a cell’s thermal stability and safety. Separators impact several battery performance parameters, including cycle life, energy and power density, and safety.
The small amount of current that may pass through the separator is self-discharge and this is present in all batteries to varying degrees. Self-discharge eventually depletes the charge of a battery during prolonged storage. Figure 1 illustrates the building block of a lithium-ion cell with the separator and ion flow between the electrodes.
Dry separator: It is manufactured by melting the polymer and then stretching it in a single direction. It is the oldest, simplest and cheapest technology of separators for Lithium-ion cells, and it is still popular today. A dry separator tends to be thicker and can have multiple layers.
Separators are getting thinner. A thickness of 25.4μm (1.0 mil) is common but some go down to 20μm, 16μm and now even 12μm without significantly compromising the properties of the cell. (One micron, also known as µm, is one millionth of a meter.) The separator with electrolyte in modern Li-ion only makes up 3 percent of the cell content.
There are three major types of separators, Dry, Coated and Wet, as described below: Dry separator: It is manufactured by melting the polymer and then stretching it in a single direction. It is the oldest, simplest and cheapest technology of separators for Lithium-ion cells, and it is still popular today.
