Compular and the EIC Accelerator: Simulating Better Batteries

Compular, based in Gothenburg, Sweden, develops software that runs and analyses molecular dynamics simulations of battery materials, automatically detecting the structures and motions of molecules that give a material its useful properties. Its EIC Accelerator project, "Advanced Simulation Software With Patented Method Optimised For Battery Development", receives an EU contribution of €2,328,679 towards a total cost of €3,326,685 and runs from July 2024 to October 2026, according to CORDIS. Before the EIC award, Compular took part in the EuroHPC-funded FF4EuroHPC programme with Chalmers Industriteknik and the battery start-up Enerpoly, according to the HPC Portal.

The project's report says Compular completed part of a multiscale model linking atomistic and continuum scales, delivered a fully automated molecular dynamics workflow ahead of schedule, deployed secure cloud infrastructure and tested early versions with pilot users, according to CORDIS. Its main result so far, the report says, is an automated web application for molecular dynamics simulations of electrolytes, Compular Lab. Local software and full multiscale integration were still at an early stage. Compular has not published customer names, revenue or funding.

Where Compular Stands Now

Compular's product runs at compularlab.com. The company's own website shows little public information, and it has announced no funding round since the EIC award. Its accounts were not accessible in free sources for this article, as the Swedish company-data sites were blocked.

The Technology: Batteries in a Computer

Molecular dynamics simulates how the molecules move and interact, and Compular's tools automate running these simulations and extracting properties from them. The EIC project aims to connect these atomistic results to larger-scale models with little empirical input. The report says the team is refactoring its CHAMPION engine to handle larger simulations.

What the EIC Award Promised, and What the Record Shows

The project runs until October 2026, so it is too early to judge it. It has produced a working web application and parts of the multiscale framework. Commercial uptake, the point of an Accelerator award, has not been made public.

The Money

The EU covers 70% of the project. The award was blended finance, but no EIC Fund investment has been announced, and Compular has not disclosed other funding.

What Cannot Be Checked

Why Europe Should Care

The EIC funded Compular to speed up battery material development in Europe by predicting properties from first principles. Its tools exist; public evidence that battery makers rely on them does not yet.
