News
[Dec. 17th 2025] Released v2. We have included the complete cycle test capacity data of the CALB dataset, facilitating further studies on this dataset.
Note: Time is (Anywhere on Earth time zone).
Here are the raw datasets for our work, "BatteryLife: A Comprehensive Dataset and Benchmark for Battery Life Prediction"
The data were originally used to predict battery life. It is also possible to use the processed datasets for other battery informatics tasks. This dataset consists of three sub-datasets: Zn-ion, Na-ion, and CALB datasets. Other details can be found in README.md under the directories of each sub-dataset.
Please note that this repository only provides the raw datasets for Zn-ion, Na-ion and CALB. Other raw data can be downloaded following the tutorial in our github repository. The official github repository for preprocessing and benchmarking is available at: https://github.com/Ruifeng-Tan/BatteryLife. If you use the data, you should cite the BatteryLife paper.
If you are interested in contributing, please contact us via email at [email protected] and [email protected].
