Recycling spent power battery is an important measure to alleviate energy shortage and environmental pollution. However, at present, there is no uniform standard for the recycling channels of spent power battery, and the construction of recycling channels of various recycling subjects is chaotic, and the mode with the highest efficiency is still inconclusive. Therefore, based on the current situation of spent power battery recycling, combined with the closed-loop supply chain channel decision-making theory, this paper studies three hybrid dual-channel recycling modes, compares and analyses the recycling rate and profit under different modes, and finally discusses the influence of different factors and recycling modes through numerical analysis. The results show that: (1) The hybrid dual-channel recycling mode of automobile alliance and third-party recycler can bring the maximum recovery rate and profit. (2) The competition between different recycling channels can not only improve the recovery rate, but will lead to the decline of the recovery rate and profit, resulting in a double loss situation. (3) Centralized decision-making brought about by cooperation can improve the total recovery rate and the total channel profit.
