Polyester separators for lithium-ion cells: Improving thermal stability and abuse tolerance

Orendorff, Christopher; Lambert, Timothy N.; Bencomo, Marlene; Fenton, Kyle R.

This work aims to address the failure modes in lithium-ion batteries that can be directly attributed to separator failure at temperatures well below the onset of thermal runaway. Polyester-based separators have been developed by an ambient temperature electro-spinning process shown in the SEM image. Resulting separators have electrochemical performance comparable to commercial polyolefin separators with greatly improved thermal stability. © 2013 WILEY-VCH Verlag GmbH & Co.
