Anyone paying attention to battery research sees sulfur come up frequently. That’s mostly because sulfur is a great storage material for lithium, and it could lead to lithium batteries with impressive power densities. But sulfur can participate in a wide range of chemical reactions, which has made it difficult to prevent lithium-sulfur batteries from decaying rapidly as the sulfur forms all sorts of unwanted materials. As a result, despite decades of research, very few lithium-sulfur batteries have made it to market.
But a team of Chinese researchers has managed to turn sulfur’s complex chemistry into a strength, making it the primary electron donor in a sodium-sulfur battery that also relies on chlorine for its chemistry. The result, at least in the lab, is an impressive energy per weight with extremely inexpensive materials.
Sulfur chemistry
Sulfur sits immediately below oxygen on the periodic table, so you might think its chemistry would look similar. But that’s not the case. Like oxygen, it can participate in covalent bonding in biological chemistry, including in two essential amino acids. Also, like oxygen, it can accept electrons from metals, as seen in some atomically thin materials that have been studied. But it’s also willing to give electrons up, forming chemical compounds with things like chlorine and oxygen.
