💡 Novelty & Significance:
This study uniquely integrates fleet projections, battery degradation, and dynamic material flow analysis to show that shared mobility's material savings depend on battery chemistry. It reveals a temporal trade-off: accelerated retirement boosts secondary supply, while second-life use delays recycling and raises near-term primary demand. This is significant for aligning shared mobility, battery choice, and circular strategies with transport decarbonization.
