Li-ion Separators

Dreamweaver patented battery separator technology utilizes EFTecTM nanofibrillated lyocell. The use of this material is a new step towards achieving a significant improvement in Li-ion battery safety.  Dreamweaver separators combine microfibers that melt with nanofibers that do not melt, and exhibit stability up to 300°C  resulting in separators with extraordinarily low shrinkage even above 300°C.  Utilization of EFTec™ technology allows to achieve high strength of the separators and their good permeability to the ions.
