Dataset Card for Battery Experimental Records

Dataset Summary

A collection of 549 battery experiments from 97 theses, including 321 successful and 228 failed experiments across 9 areas of battery research. Each record captures experimental conditions, measured outcomes, and failure causes where reported, standardized into a common schema for screening and verification research. Because published papers mostly report experiments that worked, the records pair successes with the failures that theses also document, drawn from many labs so that outcomes can be compared across research groups.

Data Fields

records has one row per experiment, and provenance has one row per experiment and field, giving each value's state, basis and source, joined on record_id. field_dictionary.csv describes every column, with its fill rate.

Group Columns
Identifiers record_id, deidentified_thesis_id, thesis_year, domain, comparison_key, material_id
Experiment experiment (what was done) and 72 condition fields covering cell, materials, electrolyte, processing and test protocol, ordered from most to least often reported, plus test_protocol_steps and processing_steps
Outcome reported_outcome (success or failure against the experiment's goal, as the researcher judged it), result, measurements, and for failures failure_type, failure_stage, failure_cause, failure_cause_basis and experiment_role
Missing values fields_not_reported, fields_not_applicable, fields_underspecified and fields_not_applied list, for each experiment, the fields without a value and why
  • Missing values are empty in every column, and the four fields_ lists say whether each was not reported or does not apply. Numeric fields have a _unit column, and values that are not plain numbers go in a _text column
  • To predict outcomes, use only experiment columns, since outcome columns reveal the answer

Data Splits

The release contains one split: full.

Getting Started

from datasets import load_dataset

records = load_dataset("GenData-Research/battery-experimental-records", "records", split="full")
provenance = load_dataset("GenData-Research/battery-experimental-records", "provenance", split="full")

failures = records.filter(lambda r: r["reported_outcome"] == "failure")

Potential Uses

  • Experimental screening (evaluate how often a method selects successful experiments and how often it lets known failures through)
  • Claim verification (check scientific claims against recorded outcomes under comparable conditions)
  • Cross-lab analysis (investigate whether patterns in experimental outcomes recur across research groups)

Dataset Creation

Curation rationale

In experimental science, running the experiment in the real world is the ultimate verifier. Yet, this can be expensive, time-consuming, and wet labs are capacity constrained. Existing experimental records offer a way to evaluate screening methods before committing lab resources. Both successes and failures are required, since successes reveal what a method can identify, while failures reveal which unsuccessful candidates it lets through. Theses are a valuable source because they document research projects beyond the successful results typically emphasized in publications. Records from multiple laboratories also allow patterns to be examined across research groups.

Source data

The records come from 97 theses (83 PhD, 8 master's and 6 not stated) submitted between 2005 and 2026 at universities in 9 countries and deposited in open repositories, selected to cover a broad range of battery research with several theses in each area. A language model extracted each experiment into the common schema, every record passed a schema validator, and every value is linked to a source passage verified to appear in the thesis, while results and causes are paraphrased, French and German theses are translated, and thesis identities are withheld on purpose but available on request. Outcomes and causes are those the researchers reported and have not been independently reproduced, and the balance of successes and failures was set during curation, so rates measured here do not reflect how often experiments succeed in practice.
