Lithium-ion batteries have become a fundamental technology across modern society. Their use ranges from consumer electronics to electric vehicles and large-scale stationary energy storage. This rapid expansion has created several challenges that are not always easy to address. Research institutions, manufacturers, testing laboratories, and service stations need to evaluate various battery parameters such as the state of health, the internal resistance, hazardous temperatures, material compositions, including those of recycled materials, and others. However, the respective measurement procedures are often proprietary, and measurement traceability and comparability across institutions and countries are most often not verified. Even though several metrological research projects have addressed this issue in the past for various measurement quantities, no metrological services have been established at national metrology institutes (NMI) up to now that support the equivalence of measurements on the basis of the CIPM-MRA.
The Consultative Committee for Amount of Substance (CCQM) launched the Task Group on Metrology for Li-ion Batteries with the aim to clarify whether the global metrology system needs to support specific measurement services related to Li-ion batteries and, if so, how this should best be achieved. The central element of the Task Group’s work has been a dedicated stakeholder workshop held jointly with the VAMAS project TWA 0, Project T5 “Key Metrological Parameters for Lithium-ion Cell Standardization,” which perfectly complemented the aim of the Task Group.
This report reviews the workshop and summarises its outcome.
