LIBS is a type of atomic emission spectroscopy for the qualitative and quantitative chemical multi-elemental analysis in real time for a wide range of applications. Quantitative analysis is based on calibration with reference materials containing different analyte concentrations. Depending on the analyte-matrix, element concentrations in the low ppm-range can be measured.

• Perform the calibration and quantification of solid samples;

• Create different programming scripts for specific types of analysis (knowledge of Python language is required).

Efficient battery recycling not only reclaims valuable materials but also minimizes environmental impact. Understanding the thermal breakdown of Li-ion battery components is vital, influencing gas composition and revealing insights into material behavior during recycling.

This master’s thesis focuses on investigating the pyrolysis of lithium-ion battery black mass under various operational conditions. • Conduct laboratory-scale pyrolysis experiments to analyze solid and gaseous products. • Apply simulations to predict fluorine compound behavior and optimize lithium recovery efficiency. • Utilize TG to monitor weight loss, phase transitions, and heat flow, identifying key thermodynamic properties during pyrolysis.
