Lithium-ion batteries with cathodes made of sulfur can, in theory, store much more energy than rechargeable batteries sold today. That means longer times between charges for electric cars and mobile devices. Now, researchers in Texas have shown that adding a layer of carbon nanotubes to one component of the battery could help overcome a host of practical challenges posed by sulfur cathodes (J. Phys. Chem. Lett. 2014, DOI: . . .
