Implementation for data driven prediction of battery cycle life before capacity degradation

Severson, K.A., Attia, P.M., Jin, N. et al. Data-driven prediction of battery cycle life before capacity degradation. Nat Energy 4, 383–391 (2019). https://doi.org/10.1038/s41560-019-0356-8

This project uses machine learning to predict battery cycle life. It achieved a 95% accuracy in classifying battery longevity by analyzing 124 cells under fast-charging conditions. The analysis involved engineering voltage-curve features and applying elastic net and logistic regression models, which improved accuracy by 50%.
