Recycling of graphite from Li-batteries has attracted increased interest due to the substantial increase in global demand. In this work, leach residues of different battery recycling solutions were characterized as one potential secondary source for graphite. Sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, and sodium hydroxide were studied (2 M and 4 M concentrations, T = 60 °C, S/L = 100g/L, t = 3 h, V = 500 mL) to evaluate their impact on graphite purity and characteristics. Battery waste was industrial lithium nickel manganese cobalt oxide-rich (NMC) black mass. It was observed that the selection of lixiviants significantly influenced the purity of the extracted graphite, indicating their varying effectiveness for this type of recycling process. The findings emphasize the importance of optimizing lixiviant choice in enhancing the recovery and quality of graphite from battery waste, contributing to more sustainable battery recycling methods.
