For the NEXTCELL project, Dr. Jannis Küpper from FEV discussed the FEV’s role in evaluating the performance and lifetime of battery cells at the full-cell level, highlighting their comprehensive testing methods, focus on safety and degradation analysis, and the importance of these evaluations for real-world application readiness.

Could you please describe what does your work in cell testing to evaluate performance and lifetime full cell level consist of?
- Our work in cell testing involves evaluating the electrical performance and lifetime of the NEXTCELL battery cell at the full-cell level. We conduct an array of tests including charge-discharge cycling, capacity retention, and rate capability tests under various conditions to simulate real-world applications. Additionally, we analyze degradation trends and probe the safety behavior to ensure the reliability and long-term performance of the NEXTCELL.”
What is the importance of those tests and what’s their current status?
- These tests are crucial for understanding the performance, durability, and safety of the NEXTCELL under real-world conditions. They help identify degradation mechanisms, demonstrate design improvement opportunities, and ensure the cells meet the application-specific requirements. The test campaign is due to start once the large-format prototypes have been successfully manufactured by the project partners and are ready for testing.

How is the cost modelling being processed within NEXTCELL?
- Our cost model estimates the total cost of the NEXTCELL by accounting for all relevant inputs, such as raw materials, manufacturing, labor, overhead, and logistics. It also includes factors like energy usage, equipment depreciation, and economies of scale. By simulating the scenario of a large-scale NEXTCELL production based in Europe, the model helps identify the main cost drivers and optimization potential.
How does FEV Consulting contribute to experimental recycling processes and green cell environmental assessment?
- We assess recycling process scalability and cost implications. Additionally, we contribute to green cell environmental assessments by evaluating the environmental impact of battery materials and processes through life cycle analysis (LCA), helping to guide sustainable cell design and supply chain decisions.
