Popis:	Used Li-ion batteries through recycling allow the recovery of deficient and expensive elements such as cobalt, nickel and lithium. The work presents the possibilities of recovering cobalt from the cathodic paste of worn Li-ion batteries. The method applied for the recovery of cathode paste is the one with ultrasonication in acidic medium. Citric acid was used as a fainting medium. The method is viable and environmentally friendly. The cathode paste obtained by processing in the oven mixed with alumina leads to the obtaining of a blue cobalt pigment.
