abstract = {To explore the potassium storage potentials of polymetallic selenides, nitrogen-doped carbon coated ZnSe/CoSe/SnSe materials was synthesized by a hydrothermal method. The core of polymetallic selenides exhibits an enhanced electrochemical activity, and a cavity in the structure alleviates the volume effect upon cycle when this compound serves as anode materials of potassium-ion batteries. Meanwhile, the conductive coating shell effectively improves the material conductivity and prevents the active substance from agglomeration during potassium storage. Compared with the uncoated material, ZnSe/CoSe/SnSe@nitrogen-doped carbon material has a better potassium storage performance. The discharge specific capacity still maintains 193 mA·h/g after 800 cycles at a current density of 1 A/g. This work could provide a guide for the design and construction of high-performance potassium ion battery anode materials.}
