Abstract

Olivine (LiFePO₄)-carbon nanofibre composites were synthesized through a combination of electrospinning and solvothermal methods. Morphology, distribution and crystal structure of these composites were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Electrochemical properties of synthesized LiFePO₄-carbon fibre composite cathodes have been studied in litium ion coin cells by means of galvanostatic cycling and cyclic voltammetry. Enhanced electronic conductivity was observed for the electrospun-LiFePO₄ nanocomposites which was eight orders of magnitude higher than pristine LiFePO₄. As compared to pristine LiFePO₄, there was significant improvement in the specific capacity (∼25% at 0.1C rate) of LiFePO₄ - carbon nanofibre composites owing to their improved conductivity.
