Advanced characterization techniques for quality control of black mass
Black mass is the starting material for hydro- and pyrometallurgical recycling of lithium-ion batteries (LIBs) produced from End-of-Life (EoL) batteries. Its recyclability depends strongly on both chemical composition and physical properties, including particle size and shape distributions, skeletal and tapped density, and specific surface area. Anton Paar's instruments Multiwave 7501, Litesizer DIA 500, Ultrapyc 5000, Ultratap 500, and Nova 800 support and enable comprehensive characterization of black mass.
With the rapid rise in electric vehicles and the growing demand for energy storage concepts, the number of end-of-life (EoL) lithium-ion batteries (LIBs) will also increase in the future. Recycling these LIBs is particularly important to close the production cycle and move towards a circular economy. In this regard, the so-called black mass, which is extracted from old batteries, is an important intermediate product on the way to recovering critical raw materials such as cobalt, nickel, and lithium. The powdered black mass is the starting product for subsequent hydro- and pyrometallurgical recycling processes, which extract these valuable components (1; 2).
In addition to the chemical composition, physical characteristics such as particle size and shape distributions, specific surface area, skeletal and tapped density are equally critical properties for assessing processability. In this context, Anton Paar's scientific instruments, Multiwave 7501, Litesizer DIA 500, Ultrapyc 5000, Ultratap 500, and Nova 800, support and enable a precise and reliable approach to comprehensively characterize black mass.
