New cathode material for Li-S batteries: sulfur-anchored azulene

Green Car Congress

A team of researchers from China and Germany have used azulene—a benzene-free and vinyl-free molecule—to polymerize with sulfur to create a cathode material for Li-S batteries. The reactions of organohalides with sodium polysulfide and sulfur with dithiols seem to be the most effective routes to obtain organosulfur polymers.
