Annotation:

Lithium and cobalt batteries are primary and secondary sources of constant readiness and are designed to provide electricity to the oil and gas industry facilities. Cobalt from spent batteries can be used for manufacturing catalysts for oil refining. Utilization of current sources is based on the method of mechanical-chemical destruction and provides a high degree of extraction of compounds from batteries. A technological scheme for recycling lithium-cobalt batteries is presented. Research has been carried out on batteries opening, breaking and grinding, followed by leaching to extract cobalt. The content of cobalt and lithium elements at each stage of battery processing is analyzed. Distilled water and citric acid were used as leaching agents. It was found that using of citric acid provides for 53,2 % of cobalt extraction from batteries.
