description: The given work is devoted to the methodology development for extracting cobalt from spent batteries, the synthesis of triple lithium oxide of transition metals, the study of the composition, morphology, structure, and electrochemical properties of synthesized cathode materials. The research set the following goals: 1. Analysis of modern scientific literature on cobalt extraction and subsequent regeneration of cathode materials from spent lithium-ion batteries. 2. Selection of the composition and mode of the cobalt extraction process. 3. Carrying out the synthesis of triple lithiated transition metal oxides based on extracted cobalt. 4. Research of synthesized materials, analysis of chemical and phase composition, morphology, electrochemical properties. The spent lithium-ion battery with a lithium cobalt cathode was dismantled, the cathode material was washed and dried for further processing. Based on the literature review, a solution and a leaching mode were selected for the extraction of cobalt from the cathode material. The analysis of the effect of processing time on the degree of cobalt leaching was carried out and the optimal mode was selected. Further, nickel, manganese and lithium salts were added to the resulting solution containing cobalt, and the synthesis of triple-lithiated transition metal oxide was carried out by the sol-gel method. The resulting material was analyzed for granulometric composition, chemical and phase composition, the structure, and morphology of the material were analyzed. Based on the synthesized cathode material, CR2032-type layouts were assembled, and an analysis of electrochemical properties, such as capacitance and cyclic life, was carried out.
