A simple procedure for wrapping sulfur particles in thin sheets of molybdenum disulfide may offer a way to capitalize on the promise of high-performance lithium-sulfur batteries, according to a study (J. Am. Chem. Soc. 2017, DOI: 10.1021/jacs.7b05371). Lithium batteries made with sulfur, a low-cost and abundant element, have the potential to store five times as much energy by weight as conventional Li-ion . . .
