摘要

Used batteries from electric vehicles contain valuable materials that can be recovered and recycled. Improper treatment of waste from Li-ion batteries of electric vehicles causes serious environmental problems. Li-ion batteries can be recycled by pyrometallurgical, hydrometallurgical, or a combination of these methods. The paper presents an analysis of the recycling possibilities of used Li-ion batteries of electric vehicles in laboratory phase research carried out on the recovery of metals from these batteries. For the recovery of metals, the direct recovery method was used by disassembling the battery, separating the components and recovering cobalt, copper and aluminum. For the recovery of cobalt, the ultrasonic separation process of the active cathodic paste in an ecological acid environment was used, and the copper and aluminum were recovered by melting in the furnace. Recycling reduces resource intensity in the supply chain with scarce and expensive raw materials and maximizes energy savings and emissions reductions. The impact of battery recycling and the reuse of the resulting materials depends on the type of battery and the technology of obtaining it, and also on the technology of its recycling.
