Digicell – Sustainable production of battery cells and packs through digital processes and AI-driven data analysis.
Creating more efficient, reliable and sustainable value chains for the production of batteries for the automotive industry – this is the aim of the new cutting-edge European research project “DigiCell”. Led by Keysight Technologies GmbH and with significant participation from the Austrian Institute of Technology AIT, a leading consortium of 13 European partners is researching innovative approaches to sustainable battery technologies.
INNOVATIONS THANKS TO DIGICELL
DigiCell optimizes manufacturing and testing processes for battery cells and packs by integrating digital processes and data-driven analytics powered by artificial intelligence (AI). This includes developing new materials measurement tools and creating digitally integrated multi-scale battery models using machine learning. The focus is not only on improving lithium-ion batteries (LiB), but also on finding innovative cellular solutions beyond lithium.
This innovative approach aims to reduce production costs, material usage and carbon footprint in production lines while improving electrochemical performance at the cell level. Thus, the project addresses key challenges in the context of new battery systems.

AIT: RESEARCH FOR THE FUTURE OF BATTERY TECHNOLOGY
The Austrian Institute of Technology AIT plays a key role in DigiCell. AIT’s central contributions include:
- Study of the mechanism of formation, evolution and degradation of the solid electrolyte interface (SEI) layer on symmetrical Mg|Mg cells using innovative characterization methods. The SEI is a passive boundary layer that forms in some batteries at the interface between the anode, made of carbon, and the electrolyte, and is created by the decomposition of the electrolyte.
- Identification of gas species produced during the cycling of silicon-carbon lithium-ion batteries, potassium batteries, and magnesium-ion batteries to support in-depth analysis of SEI layer properties.
- Understand end-of-life Li-ion cell degradation phenomena via in-depth characterization to assess the feasibility of active materials for second-life applications.
- Development of a prototype cell in a single-layer Mg ion pocket.
Martina Romio, the AIT project manager for DigiCell, summarizes:
Global demand for batteries is expected to increase significantly over the next ten years. In particular, the growing demand for battery electric vehicles poses major challenges to the industry at different levels.
“As a member of DigiCell, we want to make a significant contribution to sustainable, resource-efficient and cost-effective battery cell production in Europe – in line with the objectives of the European Green Deal.”
