Abstract:

The proposal of carbon peaking and carbon neutrality goals has accelerated China's low-carbon energy transformation, leading to the rigorous promotion of the new energy vehicle industry. The power battery, as the core component of these vehicles, is about to face a massive retirement wave in the replacement process. However, the cascade utilization of power batteries could alleviate recycling pressure and environmental pollution while maximizing the full life cycle of the battery, which is crucial for low-carbon emissions, energy savings, and environmental protection. To further improve the green and sustainable development system of cascade utilization, this paper analyzes the current policies, standards, and application scenarios of echelon utilization. The study discusses the battery recycling mode, aging principle, detection, screening, capacity configuration, control principle, battery management system, and other technologies from the aspects of battery recycling and cascade utilization of the energy storage system. Ultimately, the paper presents the problems and challenges faced by the cascade utilization of decommissioned power batteries, and constructive suggestions are made for the breakthrough of industrial technology and the formation of an industrial system. This research could help the industrial layout of cascade utilization.

Key words: retired power battery, battery recycling, cascade utilization, energy storage
