Synthesis and characterization of pure and doped electrode materials for Sodium- and Lithium-ion batteries. The research is focused on the optimization of the electrochemical performances of environmental-friendly compounds. The research aim is to find out the relation between structural, morphological, stability and electrical properties of the compounds and their electrochemical response.

Experimental activity:

  • Synthetic approach: solid-state, sol-gel, hydrothermal and solvothermal, microwave, co-precipitation, reflux techniques. Electrospinning technique for the fabrication of self-standing electrodes.
  • Characterization techniques: X-ray powder diffraction (qualitative and quantitative analysis, structural and microstructural investigation), Electron Scanning Microscopy and Energy Dispersive Spectroscopy, Transmission Electron Microscopy, IR spectroscopy, thermal techniques, surface area evaluation.
  • Electrochemical characterization: Cyclic Voltammetry, charge/discharge cycling, Impedance spectroscopy

Materials under investigation:

Pure and doped Na3MnZr(PO4)3, Na3MnTi(PO4)3, TiO2 and ZnS and composites with Carbon nanofibers.
