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. Hence, it is urgent to develop new organosulfur polymers with high sulfur content as candidates for Li-S batteries. Chen et al.
