Abstract :

Chemical Lithium-ion (Li-ion) energy sources dominate the market for second-class batteries (accumulators), almost all mobile phones and portable computers are powered by lithium cells. In addition, a new branch of the industry that generates demand for Li-ion batteries is the growing market for electric and hybrid cars. Lithium-ion batteries contain a number of valuable metals, such as Co, Li, Cu and Al. Cobalt is one of the less frequent metals in the Earthâ??s crust, hence its market value is high-80,490 $/MT and profitable recovery. Lithium recovery will be important in the perspective of the development of electric car production-the current price of 16,500 $/MT. Mass production of vehicles powered by Li-ion batteries will increase the demand for lithium, so its price will increase and the recovery will be profitable. Another argument in favor of recycling batteries is the need to protect the environment against heavy metal pollution or complex organic substances in their composition. This work presents the results of tests for the recovery of Co, Li, Cu and Al metals by chemical metallurgy using a mixture of formic acid, glutaric acid and perhydrol as leaching agents and sodium hydroxide as a precipitating agent. The conducted research led to the recovery of metals at a level above 85%.
