Synthesis of cobalt-based layered coordination polymer nanosheets and their application in lithium-ion batteries as anode materials

Abstract

Layered cobalt-based coordination polymer ([Co(tfbdc) (4,4′-bpy)(H2O)2], Co-LCP) nanosheets have been synthesized, which show an excellent performance as anode materials for lithium ion batteries.

Recent progress in metal–organic polymers as promising electrodes for lithium/sodium rechargeable batteries

“…The good cycling performance of this Zn-based CP comes from (1) multi-redox active sites including Zn(II) and conjugated carboxylates from mpca and tfbdc ligands; (2) flexible 1D chains, which provide shorter Li ions diffusion space; and (3) the reversible transformation and regeneration of CP structure. Additionally, similar battery reaction principles have been used to explain the case of Co3(HCOO)6, 86 Mn−LCP (Mn(tfbdc)(4,4′bpy)(H2O)2), 88 Cu-BDC [Cu2(C8H4O4)4]n, 89 Ni-Me4bpz ([H2Me4bpz = 3,3',5,5'-tetramethyl-4,4'-bipyrazole], 90 Zn-LMOF (Zn(4,4′-bpy)(tfbdc)(H2O)2), 91 Co-LCP (Co(tfbdc)(4,40bpy)(H2O)2), 92 and CoCOP (polycarboxylate-Co coordination polymer). 93…”

“…267 Comparing with 1D particles 87,268 and 3D porous frameworks, 2D layers structure have become increasingly attractive in recent works. 14,69,[90][91][92][123][124] 2D layer-by-layer deposited nanosheets, usually featuring with ultra-thin thickness and ultra-high specific areas, are able to offer numerous accessible reactive sites and have the potential to manufacture electrically conductive networks. 14, 269 Furthermore, conventional 2D conductive materials, such as graphene, are restricted by their component elements and difficulty in proceeding post-modification, while 2D conductive MOPs materials are charming because of the diversity in their composition and easy tailoring.…”

Layered manganese-based metal–organic framework as a high capacity electrode material for supercapacitors

“…Based on these advantages, they have potential applications in various elds, such as catalysis, 16-18 gas capture and release, 19,20 imaging and sensing, 21,22 batteries, [23][24][25] and magnetic materials. 26 In recent years, the application research of MOFs in supercapacitors has seen rapid development.…”

Transition-Metal-Triggered High-Efficiency Lithium Ion Storage via Coordination Interactions with Redox-Active Croconate in One-Dimensional Metal–Organic Anode Materials

“…On the basis of the above results, it can be stated that the two CPs are high-performance anode materials in comparison with MOF-based anode materials (Table ). ,− …”
