Cathode materials in the form of complex metal oxides LiNixMnyCo1–x–yO2 (0.3 ≤ x ≤ 0.6; 0.2 ≤ y ≤ 0.4) obtained by different methods, such as a solid state method and a method of thermal destruction of organometallic compounds in oil, are studied. The results of the elemental analysis, TGA/DSC, XRD, SEM, TEM, and electrochemical tests are presented. It is found that complex metal oxides obtained by the method of thermal destruction of organometallic compounds in oil are composed of primary nanocrystallites (up to 100 nm) coated by a nanoscale carbon layer that can significantly improve the electrochemical characteristics of the basic lithium-ion battery based thereon.
