Nonwoven separator for rechargeable batteries

Ultra-thin nonwovens let the ions flow

Freudenberg Innovation Award 2014 finalist 

Electricity is essential to modern life. Without it, hardly anything functions. Whether in cell phones, laptops or electric cars, rechargeable batteries are under particular stress. They need to be powerful, durable and – on top of everything else – safe. A wafer-thin yet extremely durable nonwoven separator with a functional ceramic impregnation keeps plus and minus poles permanently separated from each other. This minimizes the risk of short circuits or even battery fires while allowing the ions and thus the electricity to flow freely.
