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

UT Austin team demonstrates new approach to lithium sulfide cathodes for Li-S batteries

Green Car Congress

Schematic showing the chemical reduction reaction of one Li 2 S 6 molecule by lithium to form six Li 2 S molecules, involving the diffusion/driving of lithium out of the graphene layers in the graphite. The approach offers a new way to introduce lithium into the cathode in Li?S Lithium-sulfur (Li?S) S batteries.

Sulfur–TiO2 yolk-shell cathode for Li-sulfur battery shows best long-cycle performance so far

Green Car Congress

(b) Capacity retention of sulfur–TiO 2 yolk–shell nanostructures cycled at 0.5 C, in comparison with bare sulfur and sulfur–TiO 2 core–shell nanoparticles. The authors say that, to the best of their knowledge, this is the first time that a lithiumsulfur battery with this level of performance has been described.
