# 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**](https://huggingface.co/datasets/Scandium-Labs/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](https://github.com/Scandium-Labs/Scandium-Labs-Solid-State-Battery-Dataset).

## 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).

## Licensing

Scandium-authored content is CC-BY-4.0. Third-party records retain their source
licenses (Materials Project CC-BY-4.0, JARVIS-DFT CC0, OQMD CC-BY-4.0, COD CC0,
NOMAD CC-BY-4.0, **AFLOW non-commercial only**). Per-record source is in
`identity.source_db`. See `LICENSE` and `LICENSE_BREAKDOWN.md` for the full
