News

• [Apr. 22nd 2026] Released v11. The update details can be found at BatteryLife/assets/Version11_Update_Details.md at main · Ruifeng-Tan/BatteryLife.
• [Feb. 24th 2026] Released v10. The update details can be found at BatteryLife/assets/Version10_Update_Details.md at main · Ruifeng-Tan/BatteryLife.
• [Dec. 17th 2025] Released v9. We've detected a bug in the preprocessing script for the CALCE dataset that affects versions v7 and v8 (resulting in potential data loss). This has been fixed in the newly released v9. Please update immediately to avoid errors. We apologize for the inconvenience. Ref: Issue #18 in BatteryLife.
• [Nov. 29th 2025]: Released v8, fixing the problem of charge capacity columns for CALB dataset.
• [Oct. 30th 2025]: Released v7, adding SDU dataset and corrected the time_in_s column in all batteries.
• [June 3rd 2025]: Released v6, adding the complete Stanford dataset as "Stanford_2" (now including both releases of the Stanford dataset). We also corrected data statistics in the readme documents.
• [Apr. 29th 18:00 pm 2025]: We found that some "SOC_interval" records in the ISU_ILCC dataset were wrong. We have fixed the wrong "SOC_interval" records in version v5.
• [Mar. 5th 2025]: Due to some network issues, only the data since Mar. 5th, 2025 are complete. Please download the data of version v4 from Zenodo or download the datasets from Huggingface since Mar. 5th, 2025.

Here is the processed dataset for our publication, "BatteryLife: A Comprehensive Dataset and Benchmark for Battery Life Prediction".

The purpose of proposing this data is to facilitate battery life prediction research. It is also possible to use the processed datasets for other battery informatics tasks. This dataset consists of four sub-datasets: Li-ion, Zn-ion, Na-ion, and CALB datasets. It includes 990 batteries, 8 different battery formats, 59 different chemical systems, 9 different operation temperatures, and 421 different charge/discharge protocols in a uniform data format. Other details can be found in README.md in READMEs.zip. The life labels of the processed batteries are in "Life Labels.zip".

The official repository for preprocessing and benchmarking is available at: Ruifeng-Tan/BatteryLife: The official BatteryLife repository (github.com). If you use the data, you should cite the BatteryLife: A Comprehensive Dataset and Benchmark for Battery Life Prediction and the original papers that produced the data. The updated code of conduct is shown in the Github repository.
