SAN FRANCISCO, March 30, 2026 — LF Energy, in collaboration with Microsoft, has announced the release of a new standardized battery dataset through the LF Energy Battery Data Alliance (BDA), marking a significant step toward improving interoperability in battery research and development.
The dataset, contributed by Microsoft’s Surface Battery Development team, is aligned with the Battery Data Format (BDF), an emerging open standard designed to address one of the most persistent challenges in battery innovation: fragmented and incompatible data.
Why This Matters
Battery innovation has long been slowed by inconsistent data formats, siloed testing methodologies, and limited cross-lab comparability. The introduction of BDF aims to standardize how battery data is structured, shared, and analyzed across the ecosystem.
By aligning datasets to a common format, organizations can:
- Integrate data seamlessly across labs and equipment
- Reuse and validate battery models across vendors
- Reduce time and cost associated with data cleaning and reformatting
- Enable more reliable benchmarking and performance analysis
In short, BDF acts as a “common language” for battery data, unlocking faster iteration cycles in battery R&D.
Inside the Dataset
The newly released dataset focuses on lithium-ion cell architecture comparisons, providing structured insights into how design choices impact performance and degradation.
Key highlights include:
- Comparisons across End Tab, Middle Tab, and Multi Tab configurations
- T₀ (initial performance) benchmarking across architectures
- Cycle aging data, enabling analysis of long-term performance and degradation
This makes the dataset particularly valuable for researchers, battery manufacturers, and software teams building simulation or analytics tools.
A Step Toward Open Battery Infrastructure
“Standardization is foundational to accelerating battery innovation,” said Phil Hamilton. “By contributing this dataset in alignment with BDF, Microsoft is helping establish a shared framework that enables collaboration across the ecosystem.”
The release also signals growing momentum behind the Battery Data Alliance, which brings together stakeholders across industry, academia, and technology to define open standards for battery data.
Our Take
This move reflects a broader shift toward open infrastructure in climate tech.
Just as open-source software frameworks accelerated innovation in AI and cloud computing, standardized datasets like BDF could play a similar role in energy storage, a critical pillar of the energy transition.
For startups and investors, this unlocks:
- Faster development of battery analytics tools
- Improved comparability across technologies
- Lower barriers to entry for new players in battery intelligence
As battery demand continues to surge across EVs, grid storage, and consumer electronics, data standardization may become a key competitive advantage layer in the next wave of climate innovation.
Availability
The dataset is now publicly available via the Battery Data Alliance’s BDF Datastore. Organizations interested in contributing to or adopting the standard are encouraged to engage with the alliance.
