Abstract:
Composite materials based on LiFePO4 with olivine structure and Li1.3Ti1.7Fe0.3(PO4)3 with NASICON structure have been synthesized and characterized by the XRD analysis, scanning electron microscopy and impedance spectroscopy. The investigation of electrochemical behavior of obtained composites additionally coated with a thin carbon layer demonstrated that the LiFePO4-based materials doped by phosphate with the NASICON structure exhibit higher electrochemical capacity in comparison with the initial LiFePO4.
