Abstract

To address challenges in power battery recycling, the integrated application of battery swapping and secondary utilisation technology enhances both economic efficiency and environmental performance, providing crucial support for the sustainable development of new energy vehicles. Accordingly, this paper constructs separate Stackelberg game models for supply chains under distinct power structures—one for battery manufacturers and another for battery swapping operators. It examines the cascading utilisation of power batteries under these varying power structures, making decisions regarding the technical level of cascading utilisation, pricing of cascaded products, and consumer battery leasing rates. The study delves into how parameters such as battery leasing duration, cascading sensitivity coefficient, and cascading R&D cost coefficient influence both parties' profits and technical advancement. Findings reveal: (1) Extending consumer battery leasing durations reduces leasing costs while simultaneously increasing profits for both swapping operators and manufacturers. (2) At elevated re-use sensitivity coefficients, profits remain relatively high even with substantial re-use R&D cost coefficients, though sensitivity coefficients exert greater influence on profitability. (3) Battery manufacturers leading secondary technology R&D enhances secondary technology standards and reduces secondary product prices, whereas battery swapping operators leading such efforts benefits supply chain system profitability. (4) A battery manufacturer-dominated supply chain proves more advantageous for consumers in both the battery swapping and secondary markets.
