Interpretation of the policy on energy storage of retired automobile batteries

Can retired electric vehicle batteries be recycled?

Reuse and recycling of retired electric vehicle (EV) batteries offer a sustainable waste management approach but face decision-making challenges. Based on the process-based life cycle assessment method, we present a strategy to optimize pathways of retired battery treatments economically and environmentally.

How can a retired battery treatment be optimized economically and environmentally?

Based on the process-based life cycle assessment method, we present a strategy to optimize pathways of retired battery treatments economically and environmentally. The strategy is applied to various reuse scenarios with capacity configurations, including energy storage systems, communication base stations, and low-speed vehicles.

What is the evaluation of retired batteries?

The evaluation of retired batteries mainly focuses on the current state of the battery pack, which is used to decide whether the battery pack can be reused or further dismantled. The evaluation of the battery pack is divided into three parts: appearance inspection, electrical performance testing and final inspection.

What are the pathway decisions for retired EV batteries?

The pathway decisions for retired EV batteries address the lifecycles of battery research, manufacturing, reuse, recycling, and third-party services. Multiple parties can be associated with different interest concerns, forming a complex decision model.

Can a battery retirement pathway be used under heterogeneous conditions?

The development of a generally applicable battery retirement pathway, especially under heterogeneous battery retirement conditions, remains a challenge and is intensively coupled with many topics and disciplines. First, there are safety issues, including the risk of fires and chemical leaks.

Should EV batteries be retired?

However, as the battery cycles increase, it becomes unsuitable for EV use and needs to retire when its maximum available capacity decays to 80%. The retirement of a large number of EV power batteries poses a great challenge to the environment and low-carbon living, and the secondary use of batteries is now a very promising solution.
