“…Possessing direct bandgap of 2.67 eV and high exciton binding energy (21 meV) under room temperature, ZnSe as one of transition metal selenides has been widely used in photodetectors, laser diodes, solar cells, alkali metal ion batteries, sensors, and so on. [6][7][8] Unfortunately, when utilized in alkali metal ion batteries, ZnSe suffers from dramatic volume variation during cycling and low electrical conductivity, resulting in poor reaction kinetics and structural stability. Owing to its intrinsic properties, in addition with the differences in ionic radius, electronegativity, and physical/chemical properties of Li/Na/K metals, there are also certain differences in Li/Na/K-storage behaviors of ZnSe (including diffusion rate, reaction activation energy, and adsorption site, etc.…”

Transition metal selenides have been widely used in alkali metal ion batteries owing to their high specific capacities and low cost. However, their reaction kinetics and structural stability are usually poor during cycling, along with ambiguous differences in Li/Na/K-storage behaviors. Herein, it is revealed that ZnSe possesses better Na + -diffusion kinetics (including lower diffusion barrier, smaller activation energy, and higher diffusion coefficients) in comparison with Li + and K + , as evidenced by theoretical calculations and electrochemical studies. The architectural designs of ZnSe-based anode, including nitrogen-doped carbon (N,C) and 3D ordered hierarchical pores (3DOHP) to form a 3DOHP ZnSe@N,C hybrid combined with regulating solid electrolyte interphase (SEI), significantly enhance Na + reaction kinetics and accommodate volume changes. The resulting 3DOHP ZnSe@N,C electrodes exhibit outstanding rate capability and good cycling stability (241.6 mAh g −1 in sodium-ion batteries (SIBs) at 10 A g −1 after 800 cycles), originating from improved electrical conductivity and shortened ion diffusion paths, accompanied by ultrathin and stable SEI with less Na 2 CO 3 /NaF in organic components and boosted Na 2 Se adsorption as sodiation. Moreover, the Na-storage mechanism in 3DOHP ZnSe@N,C hybrid is further revealed by in situ studies. Accordingly, this study provides a new perspective for designing high-performance electrode materials for SIBs.

“…37,38 The peaks around 57.8 eV in Figure 4C,D could be attributed to the selenite phase, which can be formed by the partial oxidation of K 2 Se and ZnSe. 39 Figure 4E,F showed two peaks of K 2p 3/2 and K 2p 1/2 corresponding to K 2 CO 3 resulting from the generation of the SEI layer during the initial discharging/ charging. 28,40 In addition, ex-situ XRD analysis was conducted to support the phase transition, which was confirmed in the XPS analysis (Figure S7).…”

Transition-metal chalcogenides are prospective anode materials for potassiumion batteries. Herein, crystalline ZnSe nanocrystal-loaded hollow carbon nanospheres (ZnSe-HC) are synthesized by infiltration of zinc nitrate and selenium dioxide into hollow carbon nanospheres and subsequent selenization.The electrochemical reaction mechanism of ZnSe with K-ion is systematically examined by ex-situ X-ray photoelectron spectroscopy and transmission electron microscopy. Two samples with distinctive nanostructures, which are double-shelled hollow structure and yolk-shelled structure, can be fabricated by controlling the selenization temperature, and their K-ion storage performances are compared. The double-shelled ZnSe-HC, which is prepared at a lower temperature, exhibits superior cycling and rate performances to those of the yolk-shelled ZnSe-HC. For double-shelled ZnSe-HC, small ZnSe nanocrystals embedded in the carbon shell and dispersed over the inner carbon shell contribute to the structural stability and fast kinetics during repeated cycles. As a result, the double-shelled ZnSe-HC exhibits a stable cycling performance (400 mA h g À1 at 0.1 A g À1 after 100 cycles) and excellent rate capability (240 mA h g À1 at 3.0 A g À1 ).

With the rapid expansion of electric vehicles and energy storage markets, the rising demand for rechargeable lithium-ion batteries, as opposed to the limited reserves of lithium resources, poses a great challenge to the widespread penetration of this advanced battery technology. Some monovalent metals, such as sodium and potassium, and multivalent metals, such as magnesium, zinc, and aluminum, which are nontoxic and relatively abundant (compared to lithium), are considered as alternative guest ions to lithium ion, thus generating various new battery systems. However, the major obstacle to their large-scale applications has been a lack of suitable robust hosts to accommodate alkalis (Na+, K+) with large radius or multivalent ions (Mg2+, Zn2+, Al3+) with high electrostatic repulsions. Conversion-type materials provide a unique route to tackle this problem because of their special reaction mechanism, which is different from the traditional intercalation reaction, and flexibility for tuning operating voltage. In this Review, the superiority of conversion electrodes for post lithium-ion batteries is discussed in detail, and the recent progress of the newly developed ions batteries based on the conversion mechanism is comprehensively summarized. Finally, the remaining challenges and the perspectives on research directions of conversion electrodes are proposed to provide guidance for future materials engineering and battery design.
