Analysis of Liquid Metals by Laser Induced Breakdown Spectroscopy LIBS (Id 202)

No current offer!

The expansion of renewable energies requires innovative systems for the efficient storage and conversion of energiy. The HZDR investigates how liquid metals can be used in Liquid Metal Batteries (LMB) and thermoelectric converters (Alkali-Metal Thermo-Electric Converter – AMTEC). These system are promising candidates for future grid storages and waste heat utilisation, respectively.
In both systems, metal alloys and intermetallic phases of reactive alkali metals (lithium, potassium, sodium) are formed. Within this work, these alloys will be analysed and characterised by LIBS (Laser Induced Breakdown Spectroscopy). LIBS is a type of emission spectroskopy, where laser ablated and excited sample particles are analysed. The aim is to determine the cell performance on the basis of the state of charge and health, respectively, and derive corresponding measures for optimisation.
