| Abstract: | With the recent rapid expand of LiNi x Co y Mn z O2 battery market, the retired lithium ion batteries will gain explosive growth in the future. Therefore, the recovery of valuable metals such as cobalt, nickel and lithium in the electrode materials of LiNi x Co y Mn z O2 batteries has become another hot spot in the battery industry. This paper reviews the technological process and main methods for the recovery of the valuable metals from LiNi x Co y Mn z O2 batteries by wet process, with the focus placed on the leaching methods of valuable metals, separation and extraction of valuable metals, reutilization and leaching kinetics. The advantages and disadvantages of different processing methods are compared. In addition, economic analysis shows that the recovery of valuable metals from retired LiNi x Co y Mn z O2 batteries has considerable economic value. Finally, the methods for the recovery of the valuable metals of LiNi x Co y Mn z O2 batteries by wet process are summarized, and the important technologies in the future are briefly described, including chemical purification, automatic disassembling and classified recovery, which provides reference for the future development of recovery of LiNi x Co y Mn z O2 batteries. |
