The Battery Interface Ontology

The BIG-MAP project has developed the world’s first comprehensive ontology for electrochemistry, batteries, and related data in the Battery Interface Ontology (BattINFO). BattINFO is crucial in the context of scientific research because it allows for a standardized, structured, and comprehensive representation of battery-related knowledge. Battery technology is a rapidly evolving field, and a unified ontology can facilitate data integration and knowledge sharing among researchers, developers, and stakeholders.

A solution-mediated pathway for the growth of the solid electrolyte interphase in lithium-ion batteries

In this article, Wolfgang Wenzel and co-workers use a mesoscale simulation approach to comprehensively characterize the growth and composition of the SEI based on a chemistry-specific reaction network. They find that the organic SEI forms and grows in a solution-mediated pathway by the aggregation of SEI precursors far away from the surface via a nucleation process, which has consequences for long-term battery operation.

BIG-MAP is a 20 MEuro, 3-year project running from 1. September, 2020 to 29. February, 2024.
