Title: High rate lithium-sulfur batteries enabled by mesoporous TiO{sub 2} nanotubes prepared by electrospinning

Abstract

Graphical abstract: Mesoporous titanium dioxide nanotubes (MTDNTs) used as host for sulfur was prepared by electrospinning technique and subsequent thermal treatment. The nanotube walls of MTDNTs act as a host for sulfur and the hollow structure is favorable for the fast transmission of Li{sup +} ions. After sulfur was encapsulated into the pores of nanotube walls of MTDNTs, the MTDNTs/S composite electrode displays a relatively good cycling performance and especially excellent rate performance (about 610 mAh g-1 at 8 C). - Highlights: • Mesoporous titanium dioxide nanotubes (MTDNTs) were fabricated by electrospinning and subsequent thermal treatment. • MTDNTs was used as host for sulfur, TEM and SEM analysis showed that sulfur distributed in the meso pores of MTDNTs walls. • MTDNTs/S composite cathode delivers a reversible discharge capacity of 610 mAh g{sup −1} at a high current rate of 8 C. - Abstract: Mesoporous titanium dioxide nanotubes (MTDNTs) were prepared by electrospinning and subsequent thermal treatment. The as-synthesized MTDNTs possess anatase mischcrystal structure, hollow texture morphology, and a relatively high specific surface area of 93.6 m{sup 2} g{sup −1} with a pore volume of 0.2190 cm{sup −3} g{sup −1}.

After sulfur was encapsulated into the pores of nanotube walls of MTDNTs, the MTDNTs/S composite electrode displays a relatively good cycling performance and especially excellent rate performance (about 610 mAh g{sup −1} at 8 C). The retention capacity can be up to 74.2% when the discharge rate increases from 0.5C to 8.0 C.« less
