摘      要：Molybdenum trioxide(MoO3)is regarded as a promising electrode material for lithium(Li)-ion batteries because of its unique layered structure with a high theoretical capacity(~1117 mAh·g-1).Till now,numerous researches have focused on tuning MoO3 morphology to improve its electrochemical ***,the fabrication of MoO3 with a two-dimensional(2D)nanosheet clusters structure has yet been ***,we report a facile one-step solvothermal method to prepare MoO3 nanosheets,of which the morphology can be facilely tuned via the dose of hydrogen *** the experimental results and theoretical calculation suggest that the resultant 2D nanosheets structure could reduce the diffusion paths,which is beneficial for the intercalation of *** a result,the nanosheets assembled Li-ion battery has a reversible specific capacity of 756.1 mAh·g-1 at 0.5·g-1,and maintained at 214.7 mAh·g-1 after 600 cycles at a current density of 1 A·g-1with the Coulombic efficiency as high as 97.17%.
