Abstract: The growth of demand for power batteries will be inevitably driven by the rapid development of the new energy vehicle, and the derivative problem of battery recycling is becoming more and more prominent. However, multiple stakeholders are involved in the recycling process of power battery, and there are many problemssuch as unclear definition of recycling responsibilities, low enthusiasm of enterprises and high recycling costs. Therefore, the improvement of market system from the source prevention to the end-treatment will be a long-term process, requiring the joint efforts of multiple entities. Considering the concept of extended producer responsibility and the subject responsibility of recycling taking by the vehicle enterprise, a tripartite game model, which is based on the interests of vehicle enterprises, battery manufacturers and third-party dismantling corporations, is built in this paper. The benefit relationship of each party during green production and recycling of the waste battery is analyzed in this model. Matlab software is used to simulate the process of three-party interaction.
