Lithium sulfur: A battery revolution on the cheap?

(Nanowerk News) Whip together an industrial waste product and a bit of plastic and you might have the recipe for the next revolution in battery technology. Scientists from the National Institute of Standards and Technology (NIST), the University of Arizona in Tucson and Seoul National University in Korea have combined common ingredients to make an inexpensive, high-capacity lithium-sulfur battery that can be cycled hundreds of times without losing function (“Inverse Vulcanization of Elemental Sulfur to Prepare Polymeric Electrode Materials for Li–S Batteries”).Sulfur, often an industrial waste product, could be key to futre high-performance batteries.The new battery’s performance would be competitive in today’s marketplace, says NIST materials scientist Christopher Soles. “Five hundred cycles with the capacity we’ve shown is definitely better than what’s in your laptop today.”
