Nickel ferrite promotes capacity and cycle stability of lithium-sulfur battery

(Science China Press) Recently, Xue-Ping Gao and co-workers from Nankai University reported that nickel ferrite nanofibers via electrospinning technology are developed as novel polar host of sulfur, thus leading to high volumetric capacity and good cycle stability of the sulfur-based composite with the high tap density, due to the strong adsorption ability towards soluble polysulfides by heavy nickel ferrite.
