Abstract: In the context of the vigorous implementation of the EPR system in China, a battery gradient utilization model is created based on the battery manufacturer's recycling responsibility based on the gradient utilization characteristics of the used power battery.Then respectively under the conditions of centralized and decentralized decision-making in the supply chain, the gradient utilization of power battery is studied, and the optimal decision combination and optimal profit under different decision-making conditions are obtained. Finally, the revenue sharing contract is introduced to optimize the supply chain under the condition of decentralized decision-making. The accuracy and effectiveness of the conclusion and shared contract are further verified by a case study. The results show that under the condition of centralized decision-making, the recovery cost of power battery is positively correlated with the sales price, and negatively correlated with the recovery rate and the profit of closed-loop supply chain. Under decentralized decision-making condition, the power battery subsidy price is negatively correlated with the sales price and positively correlated with the recovery rate.
