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.

the commercialization of lithium-sulfur (Li-S) batteries has been severely hindered by the polysulfide (PS) shuttling effect whereby PSs dissolve into the electrolyte and shuttle across the separator to react with anode materials, leading to a rapidly fading capacity with repeated charge/discharge cycles. —Lei et al.
