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 operate under strongly oxidizing and reducing conditions and must be mechanically sound and able to withstand high stresses during battery assembly and operation. Figure 1: Schematic image of a separator in cylindrical Li-ion battery cell and a zoomed-in cross-section of the layered structure.
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.
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.
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.
Inorganic polymer separators have also been of interest as use in lithium-ion batteries. Inorganic particulate film/ poly (methyl methacrylate) (PMMA) /inorganic particulate film trilayer separators are prepared by dip-coating inorganic particle layers on both sides of PMMA thin films.
