Policy optimization and practical applications in blockchain-enabled electric vehicle battery recycling system

The rapid growth of the electric vehicle (EV) market underscores the urgent need for efficient battery recycling systems. Existing systems face challenges such as information asymmetry, operational inefficiencies, and environmental risks from improper disposal. This study first optimizes policy strategies using an evolutionary game-theoretic model to analyze key stakeholder interactions, then proposes a blockchain-based traceability system that enhances transparency, security, and efficiency throughout the EV battery lifecycle. Simulation results demonstrate that effective incentives and regulatory frameworks significantly improve system performance, providing a solid foundation for policy development. This research highlights blockchain's potential to advance sustainability, support net-zero goals, and promote a circular economy in the EV industry.
