Li-ion battery separators may be layered, ceramic based, or multifunctional. Layered polyolefins are common, stable, inexpensive, and safe (thermal shutdown). Ceramic oxides reduce shrinkage and particle penetration and improve wetting. Chemically active multifunctional separators may trap, attract, or dispense ions.
Ceramic separators are known for their exceptional thermal stability and mechanical strength. They find battery applications that require enhanced safety features or operate at high temperatures. Ceramic separators are made from aluminum oxide (Al2O3) or lithium aluminum titanium phosphate (LATP).
The separator is used to isolate the cathode and anode material, playing an important role in the safety of battery, which prevents internal short circuit of battery and provides lithium ions free flow channels.
These separators are typically made from polyethylene (PE) or polypropylene (PP). Polymeric separators offer excellent dielectric properties, thermal stability, and mechanical strength. They can be manufactured with different pore sizes and thicknesses to meet the specific requirements of different battery applications.
Separators woven purely from inorganic materials, especially one-dimensional inorganic materials, possess extremely high thermal stability and structural retention capabilities. The next focus is on how to improve the mechanical properties of inorganic separators to make them more suitable for battery processing.
The dry process is commonly employed for manufacturing ceramic-based battery separators. Powder Mixing: The first step in the dry process is to mix the ceramic powders with binders and additives. The composition of the mixture is carefully controlled to achieve the desired properties in the final separator.
