Project timeline

  • Complex and thorough studies of structural and transport properties, oxygen nonstoichiometry, chemical stability, as well as studies of the electronic structure - theoretical and experimental (XPS, magnetic properties, EPR, resonance photoemission spectroscopy) of the pristine NaxCoO2-y and as a function of sodium concentration.

  • Complex and thorough studies of structural and transport properties, oxygen nonstoichiometry, chemical stability, as well as studies of the electronic structure - theoretical and experimental (XPS, magnetic properties, EPR, resonance photoemission spectroscopy) of layered Li1+xV1-xO2 with different initial composition x and nonstoichiometry in oxygen sublattice, as well as after gradual intercalation of lithium.

  • Determination of the nature of anomalous electronic effects (sharp maxima on the thermoelectric power of the order of 1000 μV/K) observed in the intercalated structure of manganese spinel LixMn2O4 and demonstration of their influence on the high effectiveness of the lithium intercalation/deintercalation process.

  • Verification of the electronic model of intercalation of the alkaline metal in transition metals compounds. Elaboration of the criterion, which will allow to design the useful properties of the electrode materials for Li-ion batteries.
