With the number of electric vehicles (EVs) projected to increase 25‐fold by 2030, effective recycling processes need to be developed to conserve the critical raw materials (in particular, cobalt and lithium) used to make lithium‐ion batteries (LIBs). Industrial recycling of LIBs is underdeveloped due to two main reasons: i) complex and particularly variable cathodic chemistries; ii) physically different shapes and sizes of battery packs which are not designed for easy disassembly. Present processes use pyrometallurgical and/or hydrometallurgical recycling methods, with the latter being widely seen as the future in view of changing battery chemistries to lower cobalt contents. As such, this paper focuses on improvements, including sorting of batteries and using alternative water‐soluble binders, to enhance LIB material recovery from hydrometallurgical processes. This review promotes the adoption of a holistic design approach for LIBs that includes ease of end‐of‐life recyclability.

迈向更具可持续性的锂离子电池未来:从电动汽车回收锂电池

到2030年,电动汽车(EV)的数量预计将增长25倍,因此需要开发有效的回收流程,以保护用于制造锂离子电池(LIB)的关键原材料(尤其是钴和锂)。LIB的工业循环利用不完善的主要原因有两个:i)复杂且特别易变的阴极化学;ii)电池组的物理形状和尺寸不同,其设计不便于拆卸。当前的方法使用火法冶金和/或湿法冶金再循环方法,鉴于改变电池化学以降低钴含量,后者被广泛视为未来。因此,本文着重于改进,包括电池分类和使用替代的水溶性粘合剂,增强湿法冶金过程中LIB材料的回收率。这项审查促进了LIB的整体设计方法的采用,其中包括易于报废的可回收性。
