title: Superior electrochemical properties of MoS2 powders with a MoS2@void@MoS2 configuration.
abstract: Yolk-shell MoS2 powders with a distinct configuration of MoS2@void@MoS2 were prepared for the first time by applying spray pyrolysis. The yolk-shell MoO3 powders prepared by spray pyrolysis were converted into MoS2 powders by a simple sulfidation process at 400 °C without altering the morphology. Dense structured MoS2 powders were also prepared by a similar process. The respective initial discharge capacities of the yolk-shell and dense structured MoS2 powders at a current density of 1000 mA g(-1) were 651 and 490 mA h g(-1), and the corresponding capacity retentions after 100 cycles measured from the second cycle were 100 and 72%.
