Kevlar's heat resistance could also lead to safer batteries as the membrane stands a better chance of surviving a fire than most membranes currently in use.
Made with nanofibres extracted from Kevlar, the University of Michigan has developed a new battery technology that should be able to prevent the kind #
While the team is satisfied with the membrane's ability to block the lithium dendrites, they are currently looking for ways to improve the flow of loose lithium ions so that batteries can charge and release their energy more quickly.
The research was funded primarily by the National Science Foundation under its Chemical, Bioengineering, Environmental and Transport Systems and its Innovation Corp.
Partial funding also came from Office of Naval Research and Air Force Office Scientific Research.
