U Texas Austin team finds P2S5 electrolyte additive enables use of Li2S bulk particles for high-capacity cathodes in lithium-sulfur batteries; ~800 mAh/g

Green Car Congress

The ability to use commercially available bulk particles could significantly decrease the manufacturing cost of Li?S While Lithium-sulfur (Li-S) batteries offer the promise of a high theoretical energy of ?2500 S batteries with a Li S cathode. S batteries. 2500 Wh kg ?1 Batteries'

Drexel team proposes TiO/CNF nanofiber mats to improve Lithium-Sulfur battery performance

Green Car Congress

Furthermore, the free-standing TiO/CNF-S cathodes developed with rapid sulfur melt infiltration (~5 sec) eradicate the need of inactive elements such as binders, additional current collectors (Al-foil) and additives. We have created freestanding porous titanium monoxide nanofiber mat as a cathode host material in lithium-sulfur batteries.
