Sodium-ion batteries have long been touted as a possible successor to the lithium-ion kind—they may have lower energy density, but they rely on more abundant sodium rather than lithium, perform better in cold temperatures, and above all, tend to be cheaper. The model’s sodium battery version has a smaller battery pack (21.4

A team of researchers from institutions in China and the US report the design of a negatively charged graphene composite separator for the effective suppression of the polysulfide shuttling effect in Li-sulfur batteries. Therefore, despite extensive efforts, the improvement to date remains rather unsatisfactory, especially in energy density.

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.
