摘要:
The thin-walled hollow MoS2 microsphere was synthesized by a facile released online NH3-blowing during the reduction of ammonium tetrathiomolybdate ((NH4)2MoS4) in N-methylpyrrolidone (NMP) solvent by hydrazine hydrate at 80  and investigated electrochemically as sulfur host for lithium sulfur battery. The results show that the as-prepared MoS2 @S electrode delivers an initial specific capacity of as high as 1801 mAh g-1, albeit partly due to the formation of SEI membrane, indicating the modulation of MoS2 on the electrochemical reaction of sulfur when compared with bare sulfur electro...
