The same bulletproof material that has saved countless lives may now have another practical use in everything from smartphones to airplanes.
Researchers at the University of Michigan have used Kevlar as a barrier to create slimmer lithium-ion batteries. The result is a battery that lasts longer, is more flexible and is explosion-proof, according to Nicholos Kotov.
The University of Michigan professor, who is co-inventor of the technology, told ABC News that Kevlar was chosen as an insulator for its “high strength” and “heat resistance.”
Standard lithium-ion batteries work by sending charges between electrodes via a circuit path. When battery membrane holes become a certain size, lithium atoms can accumulate and create structures called dendrites, which poke through the membrane.
Dendrites become a problem if they reach the other electrode, which will short out the circuit. This is how some battery fires are believed to have started.
