As more countries rely on renewable energy sources, battery systems must meet rising efficiency and longevity demands to stay relevant. Knowing key performance indicators of batteries, like Round Trip Efficiency (RTE) and State of Health (SOH), are critical to optimizing their operation and increasing overall performance.
In this rapidly evolving field, while key performance indicators can be readily accessed, the performance evaluation and comparison of battery technologies remain a challenging task, due to the huge variation in the quality and quantity of data reported and the lack of a common methodology.
Whilst this development will not have an immediate impact on the benchmarking of battery technologies, it will set a best practice for the reporting of results. The impact of implementing such methodologies should become apparent within 3-4 years of its adoption in research projects and journal publications.
For a successful implementation, the suggested reporting methodology needs to be adopted by most scientists and implemented in all battery research projects for monitoring the progress beyond the state-of-the-art. Editors and Board members of high- level scientific journals could greatly assist in the implementation of such recommendations.
The document provides the basis for the development of homogenized performance metrics and a transparent reporting methodology at cell level, necessary for the reliable benchmarking of battery chemistries.
The scope of this deliverable is to define a set of Key Performance Indicators (KPI) relevant for the different segments of the battery value chain, going from new and emerging technologies to final applications, mainly for transport and stationary.
