Abstract Development and design of new batteries require numerous electrical diagnostic methods; impedance spectroscopy is a prevalent one of them. Nevertheless, there occurs to be a gap from laboratory conditions to the final application point of view due to differing accuracy requirements, data availability and data quality. This chapter provides some insight into applicability of analysis methods outside the laboratory scale. The beneficial usage of the impedance spectroscopy approach will be shown for three typical fields of application, namely state of charge determination, temperature detection as well as battery degradation analysis, while several chemistries like innovative LiS or LFP were under investigation.
