Lithium-sulfur batteries last longer with nanomaterial-packed cathode Electric vehicles could travel farther and more renewable energy could be stored with lithium-sulfur batteries that use a unique powdery nanomaterial. Researchers added the powder, a kind of nanomaterial called a metal organic framework, to the battery's cathode to capture problematic polysulfides that usually cause lithium-sulfur batteries to fail after a few charges. A paper describing the material and its...

X-ray Imaging To Observe Running Batteries In Action

Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries — a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost. But lithium-sulfur technology has a major drawback: After a few dozen cycles of charging and discharging, the battery stops working. "The cycle life of...
