Abstract:

Choosing an appropriate recycling model is the key to achieving standardized recycling of waste power batteries. According to the recycling technical route of waste power battery: recycling- echelon utilization- material recycling, a Stackelberg game model with the main recycler of a new energy vehicle(NEV) manufacturer, a power battery(PB) manufacturer and a third-party recycling enterprise respectively is constructed to solve the optimal decision and optimal profit of this three recycling models. Besides, the effect of recycled material revenue on the choice of recycling model and the carbon emission of the closed-loop supply chain system is discussed.The results show that from supply chain perspective, as recycled material revenue is below a certain threshold, when NEV manufacturer becomes the recycler is the optimal recycling model, otherwise, when PB manufacturer becomes the recycler is the optimal recycling model. Meanwhile, different recycled material revenue will lead to inconsistent choices of recycling models among supply chain members, so that coordination of supply chain profit is required to achieve a long term and consistent optimal recycling model. Moreover, when the carbon emission efficiency of power battery recycling technology is high, the optimal recycling model corresponds with the lowest carbon emission, otherwise, the optimal recycling model will cause carbon emission burden.The findings of this paper provide a reference for power battery closed-loop supply chain to select the optimal recycling model and it can also assist the government to formulate subsidy policies for the material recycling chain.

Key words: waste power batteries, recycling model, recycled material revenue, carbon emission, closed-loop supply chain
