MoS2 hollow spheres in ether-based electrolyte for high performance sodium ion battery.

In this work, instead of coupling with carbon-based materials, the obtained MoS2 hollow spheres constructed of many curved nanosheets have been successfully fabricated via one-pot hydrothermal process. Meanwhile, inheriting the advantages of hollow structure and combining the merits of ether-based electrolyte with the optimized voltage range, the obtained MoS2 electrode can demonstrate excellent electrochemical performance which deliver a large capacity, superior rate (391.4 mA h g-1 at 0.1 A g-1 and 347.3 mA h g-1 at 0.5 A g-1) and long cycling performance (334.6 mA h g-1 at 2 A g-1 after 1200 cycles) when employed as anode material for sodium ion battery.
