Possibilities of using magnetic separation to recover selected metals from the active material of Li batteries

Original language description

Currently, the focus of the waste Li-ion battery processing is on better separation of individual materialcomponents of the batteries so that this process is as efficient as possible. This step is closely related to thesuccess of the subsequent processing of the individual separated components. The active material (blackmass) after separation contains a certain proportion of metals in the form of their compounds and graphite.The paper deals with the possibility of separating a portion of selected metals, such as cobalt and nickel, intoa separated fraction of the black mass using magnetic separation. The active material was annealed at 900whereby some of the metals were converted into a ferromagnetic state. The subsequent leaching convertedthe soluble salts into solution. A wet magnetic separation method was then used to concentrate the selectedmetals into the separated fraction. From the process, a mass fraction richer in the content of selected metals,a fraction richer in graphite and, after drying the solution after leaching, a proportion of salts including lithiumsalts was obtained. The success of the process depends on a number of parameters during leaching of thematerial and subsequent magnetic separation. This process made it possible to obtain a metal concentratecontaining up to 60-70 wt% of cobalt and 2-3 wt% of nickel. The problem is to achieve better separation ofindividual components from the Li active material. Finding the best way to process waste lithium batteries isimportant for sustainable electromobility.
