With the increase in the number of waste power batteries and the occurrence of related environmental problems, battery recycling is receiving extensive attention. Driven by economic benefits, many companies have begun to deploy the waste battery processing market and government subsidies also play an essential role in battery recycling. Considering the vehicle company outsources processing tasks or invests in research and development (R&D), this paper studies the optimal decision-making problem of the supply chain under government subsidy to the battery manufacturer or the battery manufacturer. The research finds that: (1) For the government, when the vehicle company outsources processing tasks, compared with subsidizing the vehicle company, the total recycling volume when subsidizing the battery manufacturer is higher. When the vehicle company invests in R&D, the total recycling volume under different government subsidy strategies is equal. (2) The vehicle company's decision is only related to its processing costs; when the unit processing cost is low, the vehicle company's profit under the strategy of investing in R&D is higher. However, when the unit processing cost is high, the profit of outsourcing processing tasks is higher. (3) With increase in unit subsidy and decrease in unit processing cost, the total recycling volume will increase. These findings can provide decision-making help for the government in formulating subsidy policies and the vehicle company in determining processing strategies in the future.
随着废旧动力电池数量的增加和相关环境问题的出现，电池回收受到广泛关注。在经济效益的驱动下，许多公司已经开始布局废旧电池处理市场，政府补贴在电池回收中也发挥着重要作用。考虑到汽车公司将处理任务外包或投资研发，本文研究了政府对电池制造商或电池制造商进行补贴的供应链的最优决策问题。研究发现：（1）对于政府而言，当汽车公司将处理任务外包时，与补贴汽车公司相比，补贴电池制造商时的总回收量更高。当汽车公司投资研发时，不同政府补贴策略下的总回收量相等。（2）汽车公司的决策仅与其处理成本有关；当单位处理成本较低时，汽车公司在研发投资策略下的利润更高。但是，当单位处理成本较高时，外包处理任务的利润更高。（3）随着单位补贴的增加和单位处理成本的降低，总回收量将增加。这些发现可以为政府制定补贴政策和汽车公司未来确定处理策略提供决策帮助。
