With the increasing adoption of electric vehicles, their end-of-life management is a timely matter. This requires recognizing the upcoming volume of retired electric-vehicle-batteries to the waste stream. The projection is further useful if we have an estimation of the remaining value within them to categorize the recycling or repurposing potential to allow appropriate policy development and facility planning. This qualification assessment is neglected in the current literature. Neglecting the health status of retired batteries in estimating their residual value might end up over or underestimating their reuse and recycling potential. This study aims to provide a hierarchical battery waste estimation based on their health and age of disposal in Ireland. These two factors are the fundamental parameters in determining the feasibility of repurposing or recycling retired batteries. Identifying this information, we defined three reuse scenarios with different state-of-health limits. Results indicate almost 50%, 30%, and below 10% repurposing potential in the year 2050 when setting a repurposing threshold of above 80%, 85%, and 90%, respectively. The authors also highlight the effect of non-regional repurposing on the recycling potential.

随着电动汽车的日益普及，其报废管理成为一个亟待解决的问题。这需要认识到即将有大量退役电动汽车电池进入废物流。如果我们能估计出这些电池的剩余价值，以便对回收或再利用潜力进行分类，从而制定适当的政策和规划设施，那么这种预测将更有帮助。目前的文献中忽略了这种资格评估。在估计退役电池的剩余价值时忽略其健康状况可能最终导致对其再利用和回收潜力的高估或低估。本研究旨在基于爱尔兰退役电池的健康状况和报废年龄提供一种分层的电池废物估计。这两个因素是确定退役电池再利用或回收可行性的基本参数。通过识别这些信息，我们定义了三种具有不同健康状态限制的再利用情景。结果表明，到2050年，当分别将再利用阈值设定为80%以上、85%以上和90%时，再利用潜力分别约为50%、30%和低于10%。作者还强调了非区域再利用对回收潜力的影响。
