A source-linked database of all-solid-state battery electrolyte formulations and performance metrics

Abstract

This is a source-linked database of all-solid-state battery (ASSB) electrolyte formulations and their reported electrochemical performance, extracted from 1,000 peer-reviewed publications. Every record in the database is traceable to a source DOI and the reporting publication. Content • 2,764 electrolyte-formulation records (composition, component ratios, electrolyte family) • 4,654 performance records across three categories: ionic conductivity (2,559), discharge capacity (1,000), and capacity retention (1,095), each with the testing conditions required to interpret the reported value • Full source linkage: every record is tied to its paper's DOI Construction and quality control Records were extracted from the source PDFs using a large-language-model-based structured-extraction pipeline, then passed through structural-completeness and physical-plausibility filtering. A stratified random sample of 200 records (50 per category) was independently checked against the source PDFs; overall audit precision was 92.5% (95% CI [88.6, 95.9]), with category-specific precision ranging from 84.0% (discharge capacity) to 98.0% (electrolyte formulation). Access This record is openly available. At the time of deposit, it contains the items listed below rather than the full database workbook; the complete database (Publications / Formulations / Measurements sheets) will be uploaded to this same record as a new file version upon acceptance of the associated manuscript. The following items are available now, so that the database's existence, scope, and composition can be independently verified ahead of the full deposit: • source_dois.xlsx — the complete list of 1,000 source DOIs with per-paper record counts in each of the four target categories • sample_records.xlsx — a fixed-seed, stratified 5% sample of the database-ready records, independently drawn per category and reproducible from the restricted file with the included sampling seeds • summary_statistics.pdf — aggregate distribution figures (record counts, publication coverage, electrolyte-family coverage, per-paper record-count distribution, and property-value distributions) with no individual record disclosed beyond the 5% sample
