2011年可充电锂离子(Li-ion)电池市场规模为118亿美元，预计到2020年将增至500亿美元。随着消费电子以及混合动力和电动汽车的发展，锂离子电池的需求将继续增加。然而，锂离子电池并没有被广泛回收，因为目前它在经济上是不合理的(相比之下，目前超过97%的铅酸电池被回收)。到目前为止，还没有商业化的方法来经济有效地回收不同正极化学成分的锂离子电池。考虑到我国有限的资源、环境影响和国家安全，锂离子电池必须回收利用。提出了一种新的低温、高效回收锂离子电池的方法，以经济地回收锂离子电池，从而无论正极化学如何，都是商业上可行的。从回收的锂离子电池中分离和合成正极材料(锂离子电池中最有价值的材料)是本研究的重点。结果表明，所开发的回收工艺实用，回收效率高，具有工业应用的可行性。
The rechargeable lithium ion (Li-ion) battery market was $11.8 billion in 2011 and is expected to increase to $50 billion by 2020. With developments in consumer electronics as well as hybrid and electric vehicles, Li-ion batteries demand will continue to increase. However, Li-ion batteries are not widely recycled because currently it is not economically justifiable (in contrast, at present more than 97% lead-acid batteries are recycled). So far, no commercial methods are available to recycle Li-ion batteries with different cathode chemistries economically and efficiently. Considering our limited resources, environmental impact, and national security, Li-ion batteries must be recycled. A new low temperature methodology with high efficiency is proposed in order to recycle Li-ion batteries economically and thus commercially feasible regardless of cathode chemistry. The separation and synthesis of cathode materials (the most valuable material in Li-ion batteries) from the recycled components are the main focus of this study. The results show that the developed recycling process is practical with high recovery efficiencies, and that it is viable for commercial adoption.
