For the first time a new cathode material for lithium-ion batteries based on LiFePO4 / C composite with improved specific capacity was synthesized, lithium conductive phases with structures of garnet (Li6.5La3Zr1.5Nb0.5O12), perovskite (Li0.34La0.56ICi) were synthesized .3Al0.3Ti1.7 (PO4) 3) for solid lithium power sources. The technology of obtaining dense ceramic samples of lithium-conductive oxide materials with a garnet structure of cubic modification has been developed.
According to the developed methods, new coordination compounds Zn (II), Ni (II) and Mg (II) were synthesized on the basis of N-substituted hydroxamic acids, ето ketoesters of higher alcohols and higher -diketones, their physicochemical properties, structure and effect on thermo-oxidative stability of organic substrates based on vegetable fats.
A method of gradient catalytic layers for the production of membrane-electrode blocks of fuel cells for the reduction of oxygen and oxidation of hydrogen with a minimum content of platinum group metals has been developed.
It was shown for the first time that Red / Ox SmF3 / MnF2 vapor can be used as electrode materials for fluoride batteries. The theoretical specific capacity of such cells is estimated at 106 mA / g
The morphological feature of the inorganic modifier стану stannum (IV) phosphate with graphene oxide additives, which provides an expansion of the operating temperature range of polymeric proton-conducting membranes, has been established.
The influence of the nature of the substituent in the β-diketonate fragment and additional ligands on the luminescent properties of monomeric and polymeric systems is established, the general requirements for ligand systems for each lanthanide ion are formulated in order to obtain materials with high emission characteristics.
