AI Customer ServiceSeparators 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 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.
The safety issue, which is a major concern that limits battery applications, could be mitigated by increasing the separator's mechanical strength, thermal stability, and shutting the batteries down below thermal runaway temperature through various functionalization approaches.
Ceramic-coated separators and high melting point polymer materials offer some improvement in thermal stability and abuse tolerance for lithium-ion cell separators but, in general, more evaluation is needed to quantify the safety impact of these new separators.
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.
Over the last five years, cellulose-based separators for lithium batteries have drawn a lot of interest due to their high thermal stability, superior electrolyte wettability, and natural richness, which can give lithium batteries desired safety and performance improvement.
