Flower-Like MoSe(2)/MoO(2) Composite with High Capacity and Long-Term Stability for Lithium-Ion Battery
A simple method is developed for the preparation of MoSe(2)/MoO(2) composite with a flower-like structure for high-performance lithium-ion batteries (LIBs). MoSe(2) could lead to fast and facile movement of Li(+) due to its larger interlayer spacing. Meanwhile, MoO(2) could protect the lamellar stru...

Sumario: | A simple method is developed for the preparation of MoSe(2)/MoO(2) composite with a flower-like structure for high-performance lithium-ion batteries (LIBs). MoSe(2) could lead to fast and facile movement of Li(+) due to its larger interlayer spacing. Meanwhile, MoO(2) could protect the lamellar structure of MoSe(2) from being destroyed in the charging/discharging processes to maintain the required active surface to electrolytes. In addition, the flower-like structure of the composite could effectively alleviate the volume expansion during charging/discharging. As LIBs are anode material, MoSe(2)/MoO(2) composite demonstrates an excellent specific discharge capacity of 1042 mAh g(−1) after 100 cycles at 0.1 A g(−1), which is attributed to the synergistic effects of MoSe(2) and MoO(2) in the composite. |
