The object of investigation is creation electrode materials for lithium chemical power sources. The aim of the work is developing the strategy of creation oxide electrode materials for lithium chemical power sources on the base of nanotechnologies. Two directions of creation electrode materials for high-capacity lithium chemical power sources have been proposed. The first one relates to obtaining anode nanomaterials on the base of precursors synthesized from titanium dichloride solutions by hydrolysis. The other one relates to obtaining cathode nanomaterials on the base of lithium-manganese spinels, e.i. the compound overstoichiometric by lithium Li[LiqMn2-q]O4, as well as LiNi0,5Mn1,5O4, the precursors of which are complex compounds of metals with citric acid. On the base of deep electrochemical investigations the precursor thermal processing technique has been proposed for obtaining electrode materials with the best physic-chemical (minimal size of the particles and their minimal aggregation, maximal porosity) and electrochemical (specific capacity, power) properties. In particular, it has been estimated that at the discharge conditions on the titanium dioxide cathodes one can reach the current up to 3350 mА·g-1, on the spinel cathodes Li[Li0,033Mn1.967]O4 - up to 1330 mА·g-1, and on the spinel cathodes LiNi0,5Mn1,5O4 - up to 1470 mА·g-1.
