Quick Answer
BatteryLake introduces a physics-grounded curation framework for battery aging data, enabling the transformation of raw datasets into benchmark-ready assets.
Quick Take
BatteryLake introduces a physics-grounded curation framework for battery aging data, enabling the transformation of raw datasets into benchmark-ready assets. It features LLM agents for metadata extraction, a human-in-the-loop verification process, and an open benchmark of 41 datasets with standardized tasks from over 25 institutions, enhancing reproducibility and usability in battery health management.
Key Points
- BatteryLake curates battery aging data into benchmark-ready formats using LLM agents.
- Human-in-the-loop verification applies 26 schema and plausibility rules for data admission.
- Open benchmark includes 41 datasets with standardized SOH and RUL tasks.
- Framework addresses inconsistencies in public battery aging datasets for better usability.
- Publicly available resources enhance reproducibility in battery health management research.

~2 min readAbstract:Public battery aging datasets are a critical asset for advanced health management, but their practical use is often limited by inconsistent formats, unclear schemas, and metadata scattered across repositories and publications. Current curation remains largely manual and hard to reproduce, while general-purpose data integration tools miss the domain-specific semantics of electrochemical time-series data. We present BatteryLake, a governed data lakehouse that turns raw public battery data into benchmark-ready assets through an agentic, physics-grounded curation framework, with three contributions. First, LLM agents extract metadata and synthesize dataset-specific converters, grounding every output in verbatim evidence and abstaining when none supports a value. Second, a human-in-the-loop mechanism frames verification as selective prediction and gates admitted data through 26 schema, statistical, and physical-plausibility rules. Third, we release an open benchmark of 41 datasets from over 25 institutions, with standardized SOH and RUL tasks, three split protocols, and eight baseline model families.

The paper introduces Adversarial Social Epistemology (ASE) to analyze how agents manipulate trust in public communications, highlighting mechanisms that undermine the reliability of testimony and inference. It critiques existing frameworks like epistemic bubbles and misinformation diffusion, proposing a new language for understanding trust breaches and auditing inferential chains in densely interactive environments involving humans and large language models.
