| Abstract Scope |
The worldwide trend of electromobility, portable electronics, and green energy storage have accelerated the production of lithium-ion batteries. Such intensive usage led to an increasing quantity of spent batteries that need to be managed to recover critical and strategic minerals. Initial mechanical treatment of battery modules creates a black mass that contains varying oxide elements depending on the electrodes’ chemistry and a considerable quantity of metallic impurities (mostly Al, Cu and Fe). In the optic of simplifying the cathode resynthesis process from black mass, we studied the impact of these metal additives (up to 5 at%) on the carbonate co-precipitation synthesis of LiNi0.8Mn0.1Co0.1O2 precursors. Moreover, electrochemical and physical analyses were done to assess both the individual and synergistic effects of Al, Cu and Fe on the cathode materials. Results show a significant amount of hydroxides co-precipitates at the same pH as carbonates, which was quantified using a novel thermoanalytical procedure. |
