About BattINFO

Mission

Battery R&D runs on data that mostly cannot be reused: numbers locked in PDFs, spreadsheets with private column names, cycler exports whose meaning left the lab with the person who ran them. BattINFO's mission is to make battery data machine-readable, linked, and reusable, so that every cell, test, and dataset carries its own meaning and any tool or team can pick it up without asking.

We did not invent our own world. We build on open standards (EMMO, JSON-LD, JSON Schema, schema.org, DCAT, PROV) and make them usable by someone with a datasheet and an afternoon.

History

BattINFO began as an ontology: the Battery INterFace Ontology, developed in the European BIG-MAP project (part of the Battery 2030+ initiative) and now maintained as the EMMO battery domain. The ontology answered what battery concepts mean; what remained open was how a working scientist would actually use it.

This project is that answer: the implementation layer that turns the ontology into everyday tools, canonical JSON records with schemas, a Python library and CLI, automatic JSON-LD with persistent w3id.org/battinfo/… identifiers, and a publishing pipeline that ends in a citable DOI and a registry entry. It is open source (Apache-2.0) and developed in the open on GitHub.
