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.
Separators impact several battery performance parameters, including cycle life, energy and power density, and safety. The separator increases internal cell resistance, and the separator takes up valuable space inside the Li-ion, making separator optimization an important part of Li-ion design.
The resulting intrusion summary is shown in Table 1 with a specific pore volume of 0.7 cm3/g, a median pore size of 0.132 μm (132 nm), and a percent porosity of 40%, just as would be expected for a polyethylene lithium battery separator diaphragm, with a resulting calculated tortuosity
Thickness & Strength: The battery separator should be thin enough to support the battery’s energy and power density and have sufficient tensile strength to prevent being stretched or damaged during the winding process. Separator thicknesses range from 25.4μm to 12μm, depending on the chemical system, without compromising the cell properties.
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.
Separators contribute to the safety and reliability of Li-ion batteries. When comparing various separator materials, there are numerous specifications, including chemical stability, mechanical strength, wettability, thermal performance and porosity, and pore size.
