Monash researchers stabilize Li-S battery with saccharide-based binder

Green Car Congress

Researchers from the Monash Energy Institute, with colleagues from CSIRO, have used a saccharide-based binder system to develop a durable sulfur cathode with minimal polysulfide escape in a lithium-sulfur battery. We plan to make the first lithium-sulfur batteries in Australia using Australian lithium within about five years.

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.

Vanderbilt researchers find iron pyrite quantum dots boost performance of sodium-ion and Li-ion batteries

Green Car Congress

Researchers at Vanderbilt University have demonstrated that ultrafine sizes (∼4.5 nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. A paper on their work is published in the journal ACS Nano. —Douglas et al. Cohn, and Cary L.

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.
