Study on the Selection Strategy of Power Battery Recycling Model Considering Blockchain Technology Inputs

In recent years, the rapid development of new energy vehicles has been accompanied by the problem of recycling and disposal of used power batteries. The current market is flooded with informal recyclers, so some power battery manufacturers have started to invest in blockchain technology to realize the tracking of power batteries and improve the formal recycling rate. This paper constructs a closed-loop supply chain consisting of power battery suppliers, electric vehicle manufacturers and consumers, establishes two recycling modes: supplier recycling and manufacturer recycling, and comparatively analyzes the pricing decision problem of supply chain members under different recycling modes by considering consumers' traceability preference and the cost of unit blockchain verification. The study shows that the manufacturer's profit is higher than the manufacturer's recycling model under the supplier recycling model, and the supplier's profit is higher than the manufacturer's recycling model under the manufacturer recycling model.
