Abstract [en]
The paper reports a results of series of interlaboratory comparisons of low impedance measurements at frequencies relevant for electrochemical impedance spectroscopy (EIS) of commercial lithium-ion cells. Two comparisons are presented. The first, bilateral comparison has focused on low impedance standards calibration in a full complex plane using digital sampling setups. The second comparison has focused on calibration and use of commercial 4-terminal battery EIS meters. Both comparisons have covered the impedance range from 50μ℧ to 100m℧ across the full complex plane in a frequency range from 0.01Hz up to 5kHz. Finally, the paper summarizes practices identified as critical for achieving measurement compatibility among various labs. © 2023 The Authors

Note
The National Physical Laboratory (NPL, Teddington, UK) and Institute for Applied Materials - Electrochemical Technologies, Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany contributed to the experiments reported in EIS meters comparison in Section 4. Authors would also like to thank to Torsten Funck from PTB for designing and constructing the impedance simulators used in the comparison. The comparison was carried out in scope of the EMPIR project LiBforSecUse (17IND10). The project received funding from the EMPIR programme, Germany co-financed by the Participating States and from the European Union's Horizon 2020 research and innovation programme. Preparation of this publication was partly funded by Institutional Subsidy for Long-Term Conceptual Development of a Research Organization granted to the Czech Metrology Institute by the Ministry of Industry and Trade.
