Fabrication of Nb(2)O(5) Nanosheets for High-rate Lithium Ion Storage Applications

Nb(2)O(5) nanosheets are successfully synthesized through a facile hydrothermal reaction and followed heating treatment in air. The structural characterization reveals that the thickness of these sheets is around 50 nm and the length of sheets is 500 ~ 800 nm. Such a unique two dimensional structure...

description Nb(2)O(5) nanosheets are successfully synthesized through a facile hydrothermal reaction and followed heating treatment in air. The structural characterization reveals that the thickness of these sheets is around 50 nm and the length of sheets is 500 ~ 800 nm. Such a unique two dimensional structure enables the nanosheet electrode with superior performance during the charge-discharge process, such as high specific capacity (~184 mAh·g(−1)) and rate capability. Even at a current density of 1 A·g(−1), the nanosheet electrode still exhibits a specific capacity of ~90 mAh·g(−1). These results suggest the Nb(2)O(5) nanosheet is a promising candidate for high-rate lithium ion storage applications.
