New energy vehicle battery recycling strategy considering carbon emotion from a closed-loop supply chain perspective

Abstract

The negative impact of used batteries of new energy vehicles on the environment has attracted global attention, and how to effectively deal with used batteries of new energy vehicles has become a hot issue. This paper combines the rank-dependent expected utility with the evolutionary game theory, constructs an evolutionary game model based on the interaction mechanism between decision makers' emotions and decision making, and studies the recycling strategy of new energy automobile trams under the heterogeneous combination of emotions. The study shows that: (1) In addition to the establishment of effective external norms, the subjective preference of decision makers can also positively affect the recycling strategy of new energy vehicle batteries. (2) Fairness preferences can have a significant nonlinear effect on new energy vehicle battery recycling strategies by changing the utility function of decision makers. (3) When new energy vehicle manufacturers remain optimistic and new energy vehicle demanders remain rational or pessimistic, the new energy vehicle battery recycling strategy can reach the optimal steady state.

Evaluation and impact factors of international competitiveness of China’s cobalt industry from the perspective of trade networks

“…The United States, Japan, Australia, and other regions have included cobalt in their lists of critical minerals. Currently, the advancement of strategic emerging industries, such as new energy vehicles, relies heavily on the utilization of cobalt resources 9 – 12 . China, being a major producer of refined cobalt, has low reserves of cobalt resources, with a high foreign dependence rate of 97%.…”
