This paper introduces the European project LiBforSecUse, which is focused on metrology requirements for impedance spectroscopy of commercial Li-ion cells for second life applications. It focuses specifically on the achievements in the workpackage dealing with traceability of low impedance analyzers for cell impedance spectroscopy. Several low impedance mΩ-range impedance standards are described. Next, a reference digital sampling impedance bridge for mΩ-range and frequencies from 0.01 Hz to 5 kHz is presented. Finally, preliminary results of an international, interlaboratory comparison of low impedance measurements are presented.
