由于电动汽车生产的巨大增长，预计到2020年，约有25万吨电池必须处理或回收。在一年内回收这么多电池的技术是不存在的，由于电池组的不同配置，回收方法也没有标准化。如何处理锂离子电池是一个严峻的挑战，锂离子电池在电池组中嵌入了数百个或更多。此外，从电池组中回收材料对于确保电动汽车市场的增长和可持续性至关重要。期望建立一种半自动化/自动化的框架，以确保电池组的更快拆卸、电池组中电池的剩余能量的识别和检测以及从电池中回收材料。本文综述了回收电池组的两个主要基本方面：机械程序和化学回收（冶金）。本文从这两个方面对现有的回收技术进行了总结，并指出了电池组回收过程中的重要研究问题，如（i）自动化和智能化回收系统，（ii）电池组的高效和安全拆解，（iii）回收市场的混沌调控，（iv）炉渣、电解液和阳极的回收工艺，（v）工业化应用，以及（vi）开发具有不同特性的组件的新电池的回收方法。本文还提出了一个框架，推动回收过程从概念到实践，无论是政府的激励政策和有效的回收技术。
Due to enormous growth of production of electric vehicles, it is estimated by the year 2020 about 250,000 tons of battery must be disposed or recycled. The technology to recycle this much amount of batteries in a single year does not exist., neither does the methods for recycling are standardized because of different configurations of battery packs. A challenge strictly poses on how to deal with lithium ion batteries, which are embedded in hundreds or more in a battery pack. Furthermore, the recovery of materials from the battery in the pack is essential to ensure the growth and sustainability of the electric vehicle market. It is desirable to establish a framework that is semi-automated/automated for ensuring faster disassembly of battery pack, identification and detection of residual energy of batteries in packs and recovery of materials from batteries. This review paper summarizes the two main basic aspects of recycling battery packs: mechanical procedure and chemical recycling (metallurgical). The work summarizes the existing recycling technology in these two aspects and identifies important research problems in the process of recycling of pack such as (i) automatic and intelligent recovery system, (ii) efficiency and safety disassemble of battery pack (iii) Adjustment of Chaos in recycling market (iv) Recovery processes for slag, electrolyte and anode, (v) Application in industrial scale, and (vi) development of recycling methods for new batteries having components with different properties. This paper also proposes a framework to push the recycling process from conception to practicality, both on government incentive polices and effective recycling technology.
