Carbon Supported MoO2 Spheres Boosting Ultra-Stable Lithium Storage with High Volumetric Density
文献摘要：
As important ingredients in lithium-ion battery,the Coulombic efficiency and power density greatly impact the electrochemical performances.Although recent literatures have reported nano-porous materials to enhance the specific capacities,intrinsic drawbacks such as poor initial Coulombic efficiency and low volumetric capacity could not be avoided.Herein,we propose a strategy to prepare carbon supported MoO2 spheres used for lithium-ion battery with high volumetric capacity density.A high initial Coulombic efficiency of 76.5％is obtained due to limited solid electrolyte interface film formed on the exposed surface.Meantime,the sample with an optimal carbon content and a proper structural strength reveals a higher reversible capacity of 956 mA h g-1 than the theoretical capacity of crystalline MoO2(838 mA h g-1)and a high capacity retention ratio of 96.4％after 100 cycles at 0.5 A g-1.And an effective compaction capacity density(under 5 MPa)of 670 mA h cm-3 of the spheres proves its potential value in practical applications.
