# Solid-State Battery (SSB) Screening – SSL Corpus

This dataset contains crystal structures sourced from the Materials Project and
optional external structure corpora for self-supervised and weakly supervised
representation learning in solid-state battery electrolyte screening.

## Format
- Parquet (Arrow) with ZSTD compression
- One row per structure
- Fields: `mp_id`, `source`, `elements`, `atomic_numbers`, `fractional_coords`, `lattice`, `spacegroup_number`, `reduced_formula`, `tier`, and optional metadata

## Tiers
- `electrolyte_relevant`
- `general_inorganic`
- `hard_negative`
