Hollow multishelled structural NiO as a “shelter” for high-performance Li–S batteries

Abstract

The physical multiple confinement and chemical adsorption of polysulfides are realized with an interlayer composed of non-polar materials (acetylene black) and polar materials (NiO hollow multishelled structures, NiO HoMSs). The 4S-NiO HoMSs/CC-S electrodes show the highest sulfur utilizations, which are 71.64% at 0.2C and 65.86% at 1.0C. The discharge capacity is 860.4 mA h g−1 after 200 cycles, with a 73.94% capacity retention rate.
