摘要

Transition metal fluoride based nanomaterials with variety of architectures have got significant interest as a cathode material in lithium-ion batteries (LIBs) due to high theoretical e.m.f values, large surface area, and their ability to transfer electrons. However, cyclic stability, reversibility and kinetics issues limit their use on large scale applications. Herein, we have synthesized transition metal fluorides i.e. CoF2, NiF2, and NH4MnF3 nanoparticles (NPs) by co-precipitation method without surfactant at room temperature. As-prepared NPs were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), differential scanning calorimeter (DSC), Ultraviolet-Visible (UV/Vis) spectroscopy, and cyclic voltammetry (CV). The CV result shows that the electrochemical performance of NiF2 NPs (similar to 30-50 nm) is improved up to 0.12 mAg(-1) as compared to CoF2 (0.08 mAg(-1)), and NH4MnF3 (0.069 mAg(-1)) NPs respectively.
