Özet
Abstract: In the current study, the conditions for multiple processing of lithium-ion batteries were investigated. The best separation of cathode and anode material from the other internal components of the LIBs could be achieved by intensive water scraping, which resulted in an overall electrode material recovery of 92–96%. Optimum leaching conditions were selected to maximize the recovery of copper, lithium, cobalt, nickel and manganese from the electrode material. Solutions of ammonium bicarbonate and succinic acid were used as leaching agents. Using ammonium bicarbonate to leach copper from uncalcined electrode material allowed copper to get separated into a distinct product, with a recovery rate of more than 90%. Succinic acid mixed with hydrogen peroxide allowed the leaching of 92–98% of lithium, cobalt, nickel and manganese from the calcined electrode material. Thus, in this study, the concept of maximizing the turnover of process streams with the aim of minimizing the generation of additional waste has been proposed. As a part of this approach, lithium sorption on novel Zr-sorbent and the regeneration of succinic acid were studied.
