Design and Game Research on the Closed - loop Supply Chain Model for Power Battery Recycling Based on Blockchain

Based on the average lifespan of power batteries, it is projected that the volume of power battery recycling in China will, exceed 70,000 tons by 2030. However, the current power battery recycling industry still faces issues such as low efficiency, uneven technological levels, and a large number of small workshops.In the field of blockchain, the government included blockchain in the "14th Five-Year Plan" in 2021. Blockchain technology has been applied in finance, insurance, and other fields. Its decentralized nature and information traceability capabilities can significantly improve the efficiency of power battery recycling, but at the same time, it may incur certain costs.Through empirical analysis, the feasibility and advantages of the blockchain-based closed-loop supply chain model for power battery recycling are verified. The results show that this model can improve recycling.
