With the exponential expansion of electric vehicles (EVs), the disposal of Li-ion batteries (LIBs) is poised to increase significantly in the coming years. Effective recycling of these batteries is essential to address environmental concerns and tap into their economic value. Direct recycling has recently emerged as a promising solution at the laboratory level, offering significant environmental benefits and economic viability compared to pyrometallurgical and hydrometallurgical recycling methods. However, its commercialization has not been realized in the terms of financial feasibility. This perspective provides a comprehensive analysis of the obstacles that impede the practical implementation of direct recycling, ranging from disassembling, sorting, and separation to technological limitations. Furthermore, potential solutions are suggested to tackle these challenges in the short term. The need for long-term, collaborative endeavors among manufacturers, battery producers, and recycling companies is outlined to advance fully automated recycling of spent LIBs. Lastly, a smart direct recycling framework is proposed to achieve the full life cycle sustainability of LIBs.
随着电动汽车（EV）的指数级增长，锂离子电池（LIB）的处置量在未来几年有望大幅增加。有效回收这些电池对于解决环境问题并挖掘其经济价值至关重要。直接回收最近在实验室层面已成为一种有前景的解决方案，与火法冶金和湿法冶金回收方法相比，具有显著的环境效益和经济可行性。然而，就财务可行性而言，其商业化尚未实现。本文对阻碍直接回收实际应用的障碍进行了全面分析，范围涵盖从拆解、分类和分离到技术限制等方面。此外，还提出了短期内应对这些挑战的潜在解决方案。概述了制造商、电池生产商和回收公司之间进行长期合作努力的必要性，以推进废旧LIB的全自动化回收。最后，提出了一个智能直接回收框架，以实现LIB的全生命周期可持续性。
