摘要：

FeP2 and P are promising anode material for lithium and sodium ion storage, due to the high theoretical capacity. However, poor electric conductivity and severe volume expansion limit its actual performance. Herein, we prepared a flexible self-supporting anode material which is consist of FeP2, P and C heterostructure nanofibers with diameter of 150.0-200.0 nm named FeP2 & nbsp;@CNs-700. Here, well-dispersed FeP2 & nbsp;nanoparticles and amorphous phosphorus are confined in carbon nanofiber skeleton, which enhance the material's electron/ion transport and structure stability. As a result, The ...
