Abstract:
Sodium-ion (Na-ion) batteries with a non-ideal reaction kinetic anode remain a key issue currently. Here, we present a heterostructured ZnSe/Bi2Se3 nanocluster coated with carbon displaying fast reaction kinetics. An in situ Raman spectrum evidences species change during charge-discharge, and an in situ X-ray diffraction pattern verifies a good reversibility. The ZnSe/Bi2Se3/NC anode exhibits a high specific capacity of 438 mA h g-1 after 500 cycles at 0.2 A g-1, and 386 mA h g-1 after 1200 cycles at 1.0 A g-1. 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.

Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
