The gradually increased amount of battery aging data has enabled rapid development of data-driven and machine learning algorithms in battery state assessment and lifetime prediction. Despite deep commitment and broad excitement, significant gaps still exist which hinders a thorough comparison and rapid iterative of the prediction algorithm. First, the formats across many public data sources are inconsistent; second, a majority of the algorithms are close source and lack of reproducibility; Last, the definition of evaluation metrices varies under different prediction scenarios, which pose challenges to compare different algorithms and develop novel one.
