Abstract
Batteries have been identified as a key technology enabling the transition to a low-carbon economy. To achieve the EU decarbonization target by 2050, the demand for high-performance, low-cost, and sustainable batteries is rapidly growing. Several battery technologies have been proposed for different applications, e.g., automotive, aviation, maritime, etc. 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. To address this challenge, Batteries Europe stakeholders have suggested reporting methodology guidelines which, if implemented, will facilitate the identification of the most promising cell technologies while highlighting areas for improvement.
