High-performance cathode ensures stability of Li-S batteries

A team of researchers from Drexel University and Aix-Marseille University in France has found a high performance cathode material that can be used in next generation lithium-sulfur batteries. According to the researchers, the discovery could pave the way for applications in mobile devices and electric vehicles.

Lithium-sulfur batteries exhibit a high energy density which is about four times higher than that of lithium-ion batteries currently used in mobile devices. But one of the challenges facing lithium-sulfur batteries is being able find cathode materials that demonstrate long-term stability.

An international research collaboration led by Drexel's Yury Gogotsi, PhD, distinguished university and trustee chair professor in the College of Engineering and director of its Nanomaterials Research Group, has created a 2D carbon/sulfur nanolaminate that could be a viable candidate for use as a lithium-sulfur

cathode.

In a paper published in the journal Angewandte Chemie, Gogotsi, along with his colleagues at Aix-Marseille University explained their process for extracting the nanolaminate from a 3D material called a Ti2SC MAX phase.
