Separion separators

Hying, C. Separion separators for lithium batteries—safety performance. Presented at Batteries 2004, 6th Ed. Paris, June 2-4, 2004. [Pg.221]

Recently Degussa announced that they have developed Separion separators for lithium batteries by combining the characteristics of flexible polymeric separators with the advantages of chemical and thermally resistant and hydrophilic ceramic materials. Separion is produced in a continuous coating process. Ceramic materials, e.g., alumina, silica, and/or zirconia, are slip-coated and hardened onto a support. ... [Pg.381]

According to Degussa, Separion separators have an excellent high-temperature stability, superior chemical resistance, and good wettabihty, especially at low temperatures. They tested the performance and safety behavior of Separion separator in 18,650 cells and found the performance to be comparable to polyolefin-based separators. [Pg.382]

Figure 20.7 shows the SEM of the Separion separator, where the ceramic materials coated over the surface of the nonwoven bonded polymer can be clearly observed. Separion separators are weak in puncmre strength and tensile stress and lower dielectric breakdown, but reasonably high in mix-penetration strength. The separator also is weak in coating adhesion. [Pg.382]

While composite separators have excellent wettability and thermal stability, they are not suitable for cell assembly. The commercially available Separion separators have been shown to overcome some of the problems associated with manufacturing. The Separion separators essentially consist of a flexible perforated nonwoven polymeric mat with porous ceramic coating on both sides. For... [Pg.807]
