Cathodic Modification in Aqueous Phosphate­-Molibdate Solutions of Chitosan as a Way of Enhancing Hydride-Forming and Hydride-Accumulating Properties of Titanium

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.

Prospective Composite Materials for Lithium~Ion Battery Cathodes Based on~Transition Metals Oxide and Rare Earth Elements Oxides Modified with Fullerene and Fluoride Ions

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.
