Sodium-ion (Na-ion) batteries with a non-ideal reaction kinetic anode remain a key issue currently. Here, we present a heterostructured ZnSe/BiSe nanocluster coated with carbon displaying fast reaction kinetics. An Raman spectrum evidences species change during charge-discharge, and an X-ray diffraction pattern verifies a good reversibility. The ZnSe/BiSe/NC anode exhibits a high specific capacity of 438 mA h g after 500 cycles at 0.2 A g, and 386 mA h g after 1200 cycles at 1.0 A g. High-performance cells cycling at -10 °C and 50 °C are achieved. These findings will lead to important applications for developing a broad set of energy-storage materials and battery systems.
