Manganese-Based Layered Coordination Polymer: Synthesis, Structural Characterization, Magnetic Property, and Electrochemical Performance in Lithium-Ion Batteries

Manganese-based layered coordination polymer ([Mn(tfbdc)(4,4′-bpy)(H2O)2], Mn–LCP) with microporous structure was synthesized by reaction of 2,3,5,6-tetrafluoroterephthalatic acid(H2tfbdc) and 4,4′-bipyridine(4,4′-bpy) with manganese(II) acetate tetrahydrate in water solution. Mn–LCP was characteriz...

Description
Summary:Manganese-based layered coordination polymer ([Mn(tfbdc)(4,4′-bpy)(H2O)2], Mn–LCP) with microporous structure was synthesized by reaction of 2,3,5,6-tetrafluoroterephthalatic acid(H2tfbdc) and 4,4′-bipyridine(4,4′-bpy) with manganese(II) acetate tetrahydrate in water solution. Mn–LCP was characterized by elemental analysis, IR spectra, thermogravimetric analysis, X-ray single-crystal structure analysis, and powder X-ray diffraction. Magnetic susceptibility data from 300 to 1.8K show that there is a weak antiferromagnetic exchange between Mn(II) ions in Mn–LCP. As anode material, the Mn–LCP electrode exhibits an irreversible high capacity in the first discharge process and a reversible lithium storage capacity of up to about 390 mA h/g from the fourth cycle. It might provide a new method for finding new electrode materials in lithium-ion batteries
