This paper discusses the significant increase in market share in the global electric vehicle industry in recent years and the subsequent large-scale decommissioning of power batteries. Governments and industries worldwide are promoting echelon utilization of retired power lithium batteries, leading to new health assessment systems and analysis methods for battery health status. The focus is on multi-scale, multi-dimensional, and multi-physical field assessments for battery health, as well as the development of integrated multi-stage and multi-level battery health management solutions throughout the life cycle.
In recent years, a significant increase in market share has occurred in the global electric vehicle industry. These advancements will eventually lead to a large-scale decommissioning of power batteries. Global governments are actively promoting echelon utilization of retired power lithium batteries, enacting a series of policies and in-centives, and the industry has also constructed large-scale projects in line with national strategies to extend the life cycle of retired power batteries. While echelon utilization for retired power lithium batteries is complex, it involves scientific assessment and management of battery health in the full life cycle. This paper summarizes relevant studies and technical progress and reconstructs a health assessment system for the full life cycle of echelon utilization for retired power lithium batteries. By extending the definition of battery health status and improving the assessment index of battery health status, the paper proposes an analysis method of health status in multi-scale, multi-dimensional, and multi-physical fields. We also analyze safety accident reports of energy storage plants, summarize the main factors that affect battery health, and propose a solution for integrated multi-stage and multi-level battery health management throughout the life cycle. Electricity and thermal management are core foundations and humidity, dust, and salt spray management for various geographical and climatic conditions. These technologies can be fully integrated with bionic principles in future studies. With the support of global governments, gradual implementation of supporting policies, and continuous advances in management and core technologies of battery health in the full life cycle of echelon utilization for retired lithium batteries, related industries will develop rapidly in the next five to ten years.
