Electrochemical element with a cathode based on zinc-substituted lithium-iron spinel of Li0,5Fe2,5-уZnуO4 type and lithium anode allows to get a stable discharge voltage ~ 2.2 in a wide area of modifying the content of intercalated Li + per unit (up to ~ 3 , 5). For slow cooled systems of samples discharged capacity depends on the distribution of magnesium ions by octa and tetra sublattice and gets maximum value of 505.7 A o h / kg for the cell, where the sample (Li0.19Fe0.50Mg0.31)(Fe0.94Li0.41 Mg0.65)VaO4 was used as the cathode and relation of Mgocta / Mgtetra is 2:1.For electrochemical sources in the system Li / electrolyte / C maximum value of specific capacity (1450 mA o h / g) and specific energy (3400 W o h / kg) is achieved by using carbon carbonized at T = 1173 K and thermally modified at T = 773 K during 100 min.
