Abstract
In this work, core-shell structured ZnSe@NPSC nanorods were prepared with a N, P, S hetero-doped carbon shell. The design of the core-shell structure is conducive to facilitating the transport of electrons and buffering the volume expansion during charge/discharge processes, which is favourable for improving the sodium ion storage properties of ZnSe@NPSC. Therefore, it can deliver capacities of 376.67 mA h g-1 after 150 cycles at 0.5 A g-1 and 359.1 mA h g-1 after cycling for 350 cycles at 1.0 A g-1, respectively.
