Lithium-sulfur batteries have long been limited by lower operating voltage and shorter lifetime compared to traditional lithium-ion technologies. Now, system-level engineering enables the conversion of sulfur to disulfur dichloride, accessing the S+1 oxidation state, thereby delivering higher voltage and improved cycling stability.
