Solid-State Battery Electrolyte Dataset — Ionic Conductivity & Activation Energy

The Scandium Labs Solid-State Battery Electrolyte Dataset provides literature-verified ionic conductivity and activation energy labels for solid-state battery electrolyte materials across 30,000+ Li-containing structures — a provenance-tracked, ML-ready foundation for electrolyte discovery and transport-property prediction.

A unified, provenance-tracked, ML-ready dataset of solid-state battery electrolyte materials with literature-verified ionic conductivity and activation energy labels — not just another Materials Project / JARVIS structural dump. Every one of the 183 verified transport labels traces back to its source paper, page, and evidence sentence.

Honest scope: the release contains 30838 bulk structural / thermodynamic DFT records (Materials Project, JARVIS-DFT, COD, AFLOW, NOMAD, OQMD) plus 183 human-verified experimental conductivity/Ea labels across 11 solid-state-electrolyte families, 427 materials with cross-paper consensus statistics, and a 165-record gold benchmark. The scarce verified labels are the asset; the bulk DFT rows are the structure/composition backbone for featurization.

Companion Datasets

Scandium Labs SSB Dataset (this dataset) — literature-verified ionic conductivity & activation energy on the electrolyte transport bottleneck.
Scandium-Dataset — harmonized DFT structural & thermodynamic screening foundation (267,230 materials from Materials Project / OQMD / JARVIS-DFT) for the earlier discovery-stage filter before transport prediction.

Ionic Conductivity Data

The verified config holds the literature-verified σ_RT (S/cm) and activation energy Ea (eV) labels for solid-state battery electrolytes. Each record carries its source DOI, measurement temperature, measurement method, conductivity type, and sentence-level provenance evidence.

Solid-State Electrolyte Families

All 11 major families are covered: sulfides, oxides, garnets, perovskites, NASICONs, halides, argyrodites, hydrides, borohydrides, antiperovskites, and polymer/composites.

How This Dataset Was Built

An automated multi-agent pipeline: source ingestion (8 connectors) → family classification → literature mining & LLM-assisted extraction → deterministic verification (Arrhenius consistency, unit normalization, cross-paper consensus) → human review → quality scoring → validation → release. The pipeline is fully deterministic after ingestion; no LLM calls are required to reproduce any artifact. Source code and pipeline docs: Scandium Labs on GitHub.

Data Splits

Splits are grouped by composition-family key to prevent leakage between polymorphs and doped variants of the same base composition. See splits_metadata.json in the source repository for the exact assignment.

Known Limitations

98% of quality-scored records sit in a single "silver" tier — honest, not a scoring bug: experimental metadata (density, pressure, atmosphere) is sparse.
Antiperovskites, hydrides, and borohydrides are under-covered relative to sulfides/garnets — this reflects the field's publication volume, not a sampling choice.
Bulk DFT rows are not screened for solid-electrolyte relevance; check family / negative.* flags before use.
150 AFLOW rows are restricted to non-commercial use (see Licensing below).
