abstract = {A free-standing ceramic separator for lithium-ion batteries
based on synthesized and surface-functionalized boehmite
nanoparticles (AlO(OH)) was prepared by means of a pilot
coating machine. For this composite membrane, polyvinylidene
difluoride (PVdF) homopolymer was used as a binder. The
separator displays a homogeneous morphology with a thickness
of 22 µm. The mean pore size of the separator is 64 nm and
the MacMullin number is 5.1. The constant current cycling
behavior and C-rate capability up to 5 C are comparable to
those of a commercial tri-layer polyolefin separator. Even
though the mechanical properties of the ceramic separator
are in some regards comparable to those of the polyolefin
separator, however, they need to be improved so that the
ceramic separator is able to withstand the stressful cell
assembly process. Moreover, the boehmite-based ceramic
separator displays a superior wettability and thermal
stability compared to state-of-the-art polyolefin separators
and is, therefore very promising for application in
lithium-ion batteries.},
