MARCH 28, 2018

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. However, sulfur is a poor electrical conductor and can become unstable over just several charge-and-recharge cycles.
