Desired Characteristics of a Battery Separator One of the critical battery components for ensuring safety is the separator. Separators (shown in Figure 1) are thin porous membranes that physically separate the cathode and anode, while allowing ion transport.
When the battery is charging the ions moves from cathode to anode and when the battery gets discharged the ions will move in the reverse direction. The separator controls the number of ions moving between the positive and negative terminal and hence it is responsible for the leakage of ions (self-discharge) when the battery is ideal.
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.
Thickness & Strength: The battery separator should be thin enough to facilitate the battery’s energy and power density and they should also have sufficient tensile strength to prevent stretching during the winding process.
In a solid-state battery, the solid electrolyte placed between the electrodes eliminates the use of a separator. Separators are a customized product, and a cell manufacturer generally shares their requirement with a separator manufacturer. Selection of the separator for the Lithium-ion cell is an art because there are no fixed definitions.
The manufacturing process of battery separators can be broadly categorized into two methods: wet and dry. The wet process is widely used for manufacturing battery separators, especially polymeric materials. Polymer Solution Preparation: The first step in the wet process involves preparing a polymer solution.
