Abstract

Recycling of valuable metals from waste Li-ion batteries(LIBs) has recently attracted significant attention. A leaching solution obtained by leaching LIBs black mass with sulfuric acid contains copper, aluminum, manganese, cobalt and nickel. In order to remove Cu, Al and Mn from the leaching solution and recover Co and Ni, experimental work was performed using solvent extraction with Ni-D₂EHPA and Ni-PC88A as an extractant. The effects of various process parameters on pre-loading and extraction were investigated. Based on experimental designs, the parameters with the largest effects on the process performance were determined to be organic phase saponification, nickel concentration and phase ratio for pre-loading.
