Relieving electric vehicle range anxiety with improved batteries

A new nanomaterial called a metal organic framework could extend the lifespan of lithium-sulfur batteries, which could be used to increase the driving range of electric vehicles. 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. During lab tests, a lithium-sulfur battery with the new MOF cathode maintained 89 percent of its initial power capacity after 100 charge-and discharge cycles.
