dc.description.abstractHo-substituted C/LiFePO4 samples were successfully fabricated, and their structural properties were examined by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) measurements. The magnetic structure of LiFePO4 correspondence to the high spin configuration of Fe2+ ions and Ho3+ causes the increase of the mu(eff) values and suppressed the antiferromagnetic transition. The XRD analysis showed an amorphous structure due to carbon, and peaks were matched by olivine-type LiFePO4. Furthermore, the lattice volume was increased with the addition of Ho. The Ho-substituted cells show similar cycling voltammetry (CV) graphs with the CV of the undoped LiFePO4 cells. According to charge/discharge cycling measurements for constant current at room temperature, the highest capacity was obtained for LiFe0.99Ho0.01PO4. The Ho-substituted LiFePO4 has a higher C-rate when compared with the undoped LiFePO4 and so it is found that a low concentration of Ho in LiFePO4 has better battery performance and may be used in commercial batteries.en_US
