Joint European Metrology Project LibforSecUse

Li-ion batteries can still find useful applications after removal from their first use in electric vehicles, e.g. as low-cost energy storage media in conjunction with photovoltaic systems, but their uptake is hampered by the lack of accurate and cost-effective characterisation techniques. This project will develop a robust measurement procedure and the supporting metrological infrastructure to measure their residual capacity using fast and non-destructive impedance based methods. Feasibility to predict premature failure will also be investigated. Such procedures are urgently required to enable economical and ecologically reasonable use of large numbers of used Li-ion batteries available in the near future
