一种可扩展的电池回收策略，用于回收和再生废旧全固态电池中的固体电解质和阴极材料，减少能源消耗和温室气体。随着锂离子电池（LIB）的迅速普及，可持续的电池回收越来越紧迫。锂离子电池可持续发展面临的主要挑战在于，目前的锂离子电池不是为回收而设计的，因此很难设计出避免将电池分解为原材料的回收方法。因此，在下一代电池进入市场之前，探索制造和回收下一代电池的新方法是谨慎的。在这里，我们为下一代全固态电池（ASSB）开发了可持续设计和可扩展的回收策略。我们使用EverBatt模型来分析与传统回收方法相比的相对能源消耗和环境影响。我们证明了从锂金属ASSB中有效分离和回收废固体电解质和电极，并直接将其再生为可用的形式，而不会破坏其核心化学结构。然后，回收的材料被重组以制造新的电池，实现与原始ASSB相似的性能，完成循环。这项工作展示了第一个完全回收的ASSB，并为未来的可持续电池提供了关键的设计考虑。
A scalable battery recycling strategy to recover and regenerate solid electrolytes and cathode materials in spent all solid-state batteries, reducing energy consumption and greenhouse gases. With the rapidly increasing ubiquity of lithium-ion batteries (LIBs), sustainable battery recycling is a matter of growing urgency. The major challenge faced in LIB sustainability lies with the fact that the current LIBs are not designed for recycling, making it difficult to engineer recycling approaches that avoid breaking batteries down into their raw materials. Thus, it is prudent to explore new approaches to both fabricate and recycle next-generation batteries before they enter the market. Here, we developed a sustainable design and scalable recycling strategy for next-generation all solid-state batteries (ASSBs). We use the EverBatt model to analyze the relative energy consumption and environmental impact compared to conventional recycling methods. We demonstrate efficient separation and recovery of spent solid electrolytes and electrodes from a lithium metal ASSB and directly regenerate them into usable formats without damaging their core chemical structure. The recycled materials are then reconstituted to fabricate new batteries, achieving similar performance as pristine ASSBs, completing the cycle. This work demonstrates the first fully recycled ASSB and provides critical design consideration for future sustainable batteries.
