Zusammenfassung:FIELD: chemical technology; production of laminated-structure cathode materials for lithium and lithium-ion batteries. ^ SUBSTANCE: proposed method involves use of ball mills or mechanochemical activators for mixing and dispersing some metals and their surface modification with oxides of some metals using aqueous and alcohol solutions of hydroxides, oxyhydroxides, or salts of respective metals forming metal oxides when decomposed at temperatures higher than 600 °C at covering oxide content of 0.5 - 5 mole percent. Process is conducted in open air. ^ EFFECT: facilitated procedure, provision for dispensing with specific installations. ^ 9 cl, 2 dwg, 3 tbl
