Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) have been attracting great attentions and widely been exploited due to the abundant sodium/potassium resources. Hence, the preparation of high-powered anode materials for SIBs/PIBs plays a decisive role for the commercial applications of SIBs/PIBs in the future. Manganese selenides are a class of potential anode materials for SIBs/PIBs because of their small band gap and high electrical conductivity. In this work, MnSe and ReS 2 core–shell nanowires connecting by polydopamine derived carbon nanotube (MnSe@NC@ReS 2 ) have been successfully synthesized from growing ReS 2 nanosheets array on the surface of MnSe@NC nanowires, which present excellent Na + /K + storage performance. While applied as SIBs anode, the specific capacity of 300 mAh·g −1 was maintained after 400 cycles at the current density of 1.0 A·g −1 . Besides, it could also keep 120 mAh·g −1 specific capacity after 900 cycles at 1.0 A·g −1 for the anode of PIBs. These heterogeneous engineering and one-dimensional–two-dimensional (1D-2D) hybrid strategies could provide an ideal strategy for the synthesis of new hetero-structured anode materials with outstanding battery performance for SIBs and PIBs.
