Glossary of degradation modes

State of health loss is determined by the dominant aging mode rather than the sum of all modes. These default scenarios should be used as starting points and adjusted based on empirical data and application-specific requirements.

Scenario LLI LAMNE LAMPE Comment
Calendaric Ageing (Storage Ageing) 0.30 0.05 0.05 SEI growth dominant, consumes only lithium inventory (LLI).
Cycling Ageing (Normal Use Case) 0.30 0.23 0.23 All ageing modes occur similarly, but LLI slightly dominates.
Worst Case Scenario 0.05 0.30 0.05 Anode ageing (LAMNE) prominent, elevated plating risk.
Best Case Scenario 0.30 0.30 0.30 All ageing modes are balanced, most mild form of degradation.
Fast-Charging Scenario 0.30 0.18 0.12 Plating dominant, but also loss of active materials.
High-Temperature Scenario 0.30 0.10 0.10 SEI growth induced ageing leads to significant LLI.

The default aging scenarios provided in this documentation are intended as general indicators to provide guidance on screening for the impact of aged cell behaviour. Actual battery aging behaviour is highly dependent on specific cell chemistry, operating conditions, and usage patterns. Users should validate these scenarios against their specific applications and consider the inherent differences between electrode materials (e.g., graphite vs. silicon) and cathode chemistries (e.g., LFP vs. NCM).
