intercalation

The electrochemical behavior of Ti electrode in aqueous solutions containing Na₂MoO₄ + H₃PO₄ + chitosan was investigated by methods of potential – time (E–t) curves at cathodic polarisation in galvanostatic mode, currentless chronopotentiometry, optic microscopy, X­ray spectral analysis of surface and determining roughness by measuring the wetting angle.

The review of cathode materials for lithium-ion batteries is presented, the analysis of advantages and application prospects of cathode materials on the basis of lithiated transition metals oxides is carried out. A method of heterovalent modification by ions of highly negative elements, lanthanum and its analogues for improving the electrochemical indices and stability of lithium manganese spinel is proposed. The effectiveness of fullerene, lithium fluoride, fullerenes halogen derivatives as modifying additive for MnO₂ cathode materials has been noticed.
