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

Green Car Congress

Researchers in Drexel’s College of Engineering report the ability of stabilized titanium monoxide (TiO) nanoparticles in nanofibers to support high conductivity and to bind polysulfides in Li-S batteries. We have created freestanding porous titanium monoxide nanofiber mat as a cathode host material in lithium-sulfur batteries.
