Abstract Direct recycling of lithium-ion is a promising method for manufacturing sustainability. It is more efficient than classical methods because it recovers the functional cathode particle without decomposition into substituent elements or dissolution and precipitation of the whole particle. This case study of cathode-healing™ applied to a battery recall demonstrates an industrial model for recycling of lithium-ion, be it consumer electronic or electric vehicle (EV) batteries. The comprehensive process includes extraction of electrolyte with carbon dioxide, industrial shredding, electrode harvesting, froth flotation, cathode-healing™ and finally, building new cells with recycled cathode and anode. The final products demonstrated useful capability in the first full cells made from direct recycled cathodes and anodes from an industrial source. The lessons learned on recycling the prototypical chemistry are preliminarily applied to EV relevant chemistries.

来自锂离子电池召回的直接回收案例研究

摘要 锂离子的直接回收是一种有前途的制造可持续性方法。它比传统方法更有效,因为它可以在不分解为取代元素或整个颗粒溶解和沉淀的情况下回收功能性阴极颗粒。该阴极修复™ 应用于电池召回的案例研究展示了锂离子回收的工业模型,无论是消费电子电池还是电动汽车 (EV) 电池。综合过程包括用二氧化碳提取电解质、工业粉碎、电极收集、泡沫浮选、阴极修复™,最后用回收的阴极和阳极构建新电池。最终产品在第一个由工业来源的直接回收阴极和阳极制成的全电池中展示了有用的能力。
