University of Texas team has found that using coaxial nanotubes can improve the performance of lithium-sulfur batteries (Li-S).They used Polypyrrole-MnO2 coaxial nanotubes to overcome obstacles to using Li-S batteries in commercial products. Prior research has shown that Li-S batteries would offer users of electronics more energy storage—as much as 5X that of lithium-ion batteries...
