Self-assembly of carbon nanotubes on a hollow carbon polyhedron to enhance the potassium storage cycling stability of metal organic framework-derived metallic selenide anodes

Research progress on ZnSe and ZnTe anodes for rechargeable batteries

“…80 Incorporation with carbon is a facile but most effective way to boost the performance of ZnSe-based PIBs, and most studies are now focused on ZIF-8-derived ZnSe hybrids. 50,132 Besides the nanoparticles, some other low-dimensional nanostructures have also been designed to address these problems, e.g., 1D ZnSe@C porous nanorods and nanofibers. 35,78 Via a self-sacrificial template (Zn 2 GeO 4 nanorod)-directed approach followed by hydrothermal selenization, uniform porous core-shell ZnSe@C nanorods could be prepared.…”

“…(g) High-rate cycling performance of ZnSe@i-NMC@o-rGO at 2. an enhanced performance in some aspects, e.g., MOF-5 derived ZnSe-FeSe 2 /rGO nanocomposites 131 and Zn-Co-Se@NCP (NCP: N-doped hollow carbon polyhedra). 132 The improved performance can be attributed to the synergistic effect between the components, i.e., relieved stress due to different reaction potentials in the insertion/extraction process, enhanced electrochemical stability and charge transfer.…”

Bimetallic Cobalt–Nickel Selenide Nanocubes Embedded in a Nitrogen-Doped Carbon Matrix as an Excellent Li-Ion Battery Anode

“…23−25 For example, Wang et al synthesized a Zn−Co−Se@NCP nanocomposite material from a ZIF-8@ ZIF-67 precursor, which delivered a discharge capacity of 410 mA h g −1 at 0.1 A g −1 . 26 Zhu et al fabricated Ni 0.33 Co 0.67 Se hollow nanoprisms, and the discharge capacity was 1575 mA h g −1 at 0.1 A g −1 . 27 Yang et al prepared a layered porous Ni− Co−Se/C material, which retained a discharge capacity of 2061 mA h g −1 at 0.1 A g −1 after 300 cycles.…”

“…Recently, metal–organic frameworks (MOFs) have been used as templates to synthesize bimetallic selenide nanomaterials because MOFs have the advantages of large specific surface area, uniform porous structure, controllable morphologies, and so forth. − For example, Wang et al synthesized a Zn–Co–Se@NCP nanocomposite material from a ZIF-8@ZIF-67 precursor, which delivered a discharge capacity of 410 mA h g –1 at 0.1 A g –1 . Zhu et al fabricated Ni 0.33 Co 0.67 Se hollow nanoprisms, and the discharge capacity was 1575 mA h g –1 at 0.1 A g –1 .…”
