Project description
Digital twins for zero-defect Li-ion battery cell manufacturing
Li-ion batteries play a crucial role in Europe’s energy transition, yet production dominance lies with China, Korea, and Japan. To counter this dependency, Europe plans to establish 25 new gigafactories amounting to EUR 35 billion by 2030. However, defects are anticipated to occur at rates ranging from 15 % to 30 % during the initial ramp-up phase. In response, the EU-funded BATTwin project aims to mitigate defect rates in battery production by implementing a comprehensive approach. This involves integrating a multi-sensor data acquisition and management layer, a Digital Battery Passport data model, process-level digital twins, and system-level digital twins to facilitate Zero-Defect Manufacturing. The platform incorporates user-centric, goal-driven digital twin workflows to guide users in system design and control.
Objective
Li-ion batteries are fundamental components for the energy transition of the European eco-system. Currently Europe lags behind Asia in terms of Li-ion battery cell manufacturing and more than 90% of the world's production takes place in China, Korea and Japan. To overcome this situation, there is an ambitious ramp-up plan of 25 new gigafactories in Europe with an expected value of €35 billion by 2030. However, in the ramp-up phase of these Gigafactories, a massive production of defects is expected, between 15% - 30%. The new European Gigafactories will also bring demand for €150 bn of battery manufacturing equipment. To support this demand, the EU production equipment industry needs to fill the current knowledge gap and gain competitiveness towards Asian providers, grounding on its world-wide leadership in high-tech, green technologies, enhanced by industry 4.0 digital solutions, exploiting the European Zero-Defect Manufacturing paradigm. The objective of BATTwin is to support this scenario by developing a novel Multi-level Digital Twin platform towards Zero-Defect Manufacturing in battery production, that will reduce defect rates in battery production lines. The solution integrates four pillars, namely (i) a multi-sensor data acquisition and management layer, supported by data semantics through a Digital Battery Passport data model, (ii) process-level digital twins, modeling the critical stages of electrode manufacturing, cell assembly and conditioning through multi-physics, data-driven and hybrid approaches, (iii) system-level digital twins, based on simulation and analytical modeling, (iv) user-centric, goal-driven digital twin workflows, increasing the explainability of digital twins and driving the user in system design and control. The approach will be tested in two industrial pilots producing different battery chemistries and geometries, validating the flexibility and scaleability of the approach towards Zero Defect European Gigafactories.
