Mesoporous MnO/C–N Nanostructures Derived from a Metal–Organic Framework as High-Performance Anode for Lithium-Ion Battery

Abstract

By application of newly designed ligand 5-(3-(pyridin-3-yl)benzamido)isophthalic acid (HPBI) to react with Mn(NO) under solvothermal conditions, a 2-fold interpenetrated Mn-based metal-organic framework (Mn-PBI) with rutile-type topology has been obtained. When treated as a precursor by pyrolysis of Mn-PBI at 500 °C, mesoporous MnO/C-N nanostructures were prepared and treated as an lithium-ion battery anode. The MnO/C-N manifests good capacity of approximately 1085 mAh g after 100 cycles together with superior cyclic stability and remarkable rate capacity, which is supposed to benefit from a large accessible specific area and unique nanostructures. The remarkable performances suggest promising application as an advanced anode material.

Octagonal Flower‐like CuO/C/NF Nanocomposite as a Self‐Supporting Anode for High‐Performance Lithium‐Ion Batteries

“…We further reveal the surface features of the product through TEM images, as shown in Figure g–h, which exhibit hollow structure in the center of the double‐layer structure, carbon generated by the calcination of PVP and organic molecules is in the outer layer with thickness of 50 nm, which as shell completely wrapped up CuO. This nanoscale carbon coating can improve the electrochemical properties of the material …”

“…This nanoscale carbon coating can improve the electrochemical properties of the material. [19] Figure 6a presents the Barrett-Joyner-Halenda (BJH) pore size distribution of cube and octagonal flower-like CuO/C/NF nanocomposites. The corresponding pore size curves show that the average pore size of cube and octagonal flower-like CuO/C/NF are 10.5 nm and 41.6 nm, respectively.…”

Progress and Perspective of Metal‐ and Covalent‐Organic Frameworks and their Derivatives for Lithium‐Ion Batteries

“…Such carbon coated bi‐metal oxides exhibit stable capacity retention and good rate capacity (762 mAh g −1 at 10 A g −1 ), which is much better than graphite on both capacity and rate performance, making it a promising candidate for LIB anode. Additionally, MnO/C−N, [126] MnO@C [119,127] (in Figure 5b), Co‐MOF derived Co/Co 3 O 4 @N−C, [128] porous Ge−Fe bimetal oxide nanowires, [129] Cr 2 O 3 /carbon [130] and NiO/Ni/Graphene [131] are also illustrated as promising MOF derived TMO/C composites as anodes for Li storage.…”

Four new Zn(ii) and Cd(ii) coordination polymers using two amide-like aromatic multi-carboxylate ligands: synthesis, structures and lithium–selenium batteries application

“…Organic ligands 5-(3-(pyridin-3-yl)benzamido)isophthalic acid (3-H 2 PBI) and 5-(3-(pyridin-4-yl)benzamido)isophthalic acid (4-H 2 PBI) were synthesized according to reported methods. 26,27 Infrared spectra were collected with KBr pellets on a Nicolet/ Nexus-670 FT-IR spectrometer. Elemental analyses were obtained by a PerkinElmer 240 elemental analyzer.…”
