UT Austin team improves performance of Li-sulfur battery

Researchers in UT Austin’s Department of Mechanical Engineering have developed an electrode for lithium-sulfur batteries that improves cyclic stability and rate capability. As published in the American Chemical Society’s journal Nano Letters, the team used polypyrrole–manganese dioxide coaxial nanotubes to encase the sulfur in the battery. The lithium–sulfur batteries still face many challenges, such as poor conductivity of sulfur, but researches are developing unique approaches to solving these issues.
