황재호, 이상엽, 이소영, 손호상
Korean J. Met. Mater. 2025;63(6):430-436.   Published online 2025 Jun 5
DOI: https://doi.org/10.3365/KJMM.2025.63.6.430

Abstract
With the growing demand for LIBs (lithium-ion batteries) for EVs (electric-powered vehicles), it will be important to recover valuable metals from spent lithium-ion batteries in the future. The black mass recovered from spent lithium-ion battery contains elements such as Li, Ni, Co, and Mn with C. The carbon in the..... More

Korean J. Met. Mater. 2024;62(7):503-510.   Published online 2024 Jun 28
DOI: https://doi.org/10.3365/KJMM.2024.62.7.503

Abstract
This study investigated the effect of a Ni-P coating layer on the solidification cracking behavior of Cu–mild steel dissimilar welds during the manufacturing of cylindrical Li-ion battery packs for electric vehicles. Four Cu plates were prepared and characterized: uncoated Cu and three levels (12, 50, and 100 μm) of Ni–P-coated..... More

                
Selective Extraction of Cu(II) from the Hydrochloric Acid Leaching Solution of Spent Lithium-Ion Batteries by a Mixture of Aliquat 336 and LIX 63
Jiangxian Wen, Man Seung Lee
Korean J. Met. Mater. 2022;60(10):751-759.   Published online 2022 Sep 29
DOI: https://doi.org/10.3365/KJMM.2022.60.10.751

Abstract
The smelting reduction of spent LIBs produces metallic alloys containing Co, Cu, Fe, Mn, and Ni. These metallic alloys can be completely dissolved by 2 M HCl solution containing H2O2 as an oxidizing agent. Extraction of the leaching solution with D2EHPA results in a Fe(III) free raffinate. In this work,..... More
