Moreover, the stronger bonding energy of Ni-O than Li-O leads to the compression of space in the Li layer, which ultimately deteriorates the rate performance [69], [70]. The slow Li + kinetics contributes to irreversible capacity loss during the first cycle [71], [72], [73] .

Over time, their capacity to store energy deteriorates, resulting in shorter battery life. But when exactly does a battery expire? The answer to this question depends on various factors, including the type of battery, its usage patterns, and the conditions it is exposed to. Generally, rechargeable batteries such as lithium-ion batteries have a limited lifespan of about
To improve the recovery rate of power batteries and analyze the economic and environmental benefits of recycling, this paper introduced the SOR theory and the TPB and constructed the system dynamics model of power battery recycling for new-energy vehicles. Through dynamic simulation, the following main conclusions were obtained.
Second-life batteries are those taken away from electric vehicles when they do not have sufficient energy and power density to propel electric vehicles.
If the batteries of retired new-energy vehicles are not effectively recycled, it will cause a great waste of resources , as surplus electricity is a crucial factor that affects the development of stand-alone renewable energy systems and batteries are the primary devices used to manage this surplus .
Thus, including consumers' preferences for remanufactured EVBs in the model would help assess and mitigate the bias of market demand and production capacity because of over-subsidies. Finally, this study assumes that the quality of returned batteries is predetermined.
The recycling of used power batteries is not only related to the response to the waste crisis, sustainable use of resources and environmental protection 11, 12, but also the key to effectively alleviate the challenges of scarce resources such as nickel, lithium, cobalt and manganese under the trend of cobalt-rich nickel 13, 14.
Therefore, the European Union, one of the largest EV markets, has proposed targets for collecting and recycling batteries of approximately 85% and 50%, respectively.
The study shows that: In the new energy vehicle battery recycling system, the battery recycling is often in a non-coordinated state due to the fact that there is no unanimous cooperation between multiple actors, which leads to a non-Pareto-optimal evolution trend in the system evolution.
