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

Abstract

Cobalt-based layered coordination polymer ([Co(tfbdc)(4,4′-bpy)(H2O)2] Co-LCP) nanosheets have been synthesized by a solvothermal method (H2tfbdc = tetrafluoroterephthalic acid, 4,4′-bpy = 4,4′-bipyridine). Powder X-ray diffraction, elemental analysis, IR spectra, thermogravimetric analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and the Brunauer–Emmett–Teller (BET) surface measurements were used to characterize the material. As an anode material for lithium-ion batteries, the Co-LCP nanosheets electrode exhibits higher reversible capacity and excellent cyclic stability, retaining 545 mA h g−1 after 50 cycles at a current density of 50 mA g−1.
