Data is at the core of battery innovation. The Battery Data Alliance invites researchers, labs, and organizations to share datasets that support transparency, reproducibility, and progress in the field. Whether you’re contributing raw test data, curated benchmarks, or metadata-rich experiment records, we provide tools and guidelines to ensure your data is stored responsibly, cited properly, and remains useful to the community. Contributors can choose open or controlled access options, and all data is versioned, validated, and aligned with Alliance standards for interoperability.
