UT Dallas researchers use 2D MoS2 as protective layer for Li-metal anodes in Li-S batteries; extended cycle life

Green Car Congress

Researchers at The University of Texas at Dallas have used two-dimensional (2D) MoS 2 (molybdenum disulfide) as a protective layer for Li-metal anodes, greatly improving the performances of Li–S batteries. This approach, they suggested, could lead to the realization of high energy density and safe Li-metal-based batteries. Chae et al.
