Abstract
- In this work, we have developed a simple and facile method to synchronously synthesize hollow FeSe<subscript>2</subscript>/C nanospheres using the Kirkendall effect. When evaluated as an anode for SIBs, the hollow FeSe<subscript>2</subscript>/C nanospheres exhibit a high discharge capacity retention of 474.1 mA h g<superscript>−1</superscript> at 0.05 A g<superscript>−1</superscript> (based on the calculation of FeSe<subscript>2</subscript>), which is very close to the theoretical capacity of FeSe<subscript>2</subscript> (∼500 mA h g<superscript>−1</superscript>). Meanwhile, hollow FeSe<subscript>2</subscript>/C also has a superior rate capability of 364.5 and 316.5 mA h g<superscript>−1</superscript> even at 2.0 and 5.0 A g<superscript>−1</superscript>, respectively. The high performance of the hollow FeSe<subscript>2</subscript>/C nanospheres can be ascribed to the unique carbon coated hollow nanostructure. [ABSTRACT FROM AUTHOR]
