Description
Summary:MnSe@SnSe2@N–C nanorods coated with nitrogen-doped carbon was successfully synthesized by simple nucleation self-assembly, carbon coating, and in situ selenization methods. In the initial cycle, MnSe@SnSe2@N–C anodes exhibit a high reversible capacity of 704 mA h g–1 at 0.2 A g–1, and after 2000 cycles, they also show an outstanding cycling stability of 417.5 mA h g–1 at 2 A g–1. Nitrogen-doped carbon mainly was used as a space buffer layer to limit volume expansion and improve the stability of cycling performance, while MnSe plays an important role in the larger capacitance. In short, MnSe@SnSe2@N–C is a promising anode material for high-efficiency lithium-ion batteries.
