Global concerns about pollution reduction, associated with the continuous technological development of electronic equipment raises challenge for the future regarding lithium-ion batteries exploitation, use, and recovery through recycling of critical metals. Several human and environmental issues are reported, including related diseases caused by lithium waste. Lithium in Li-ion batteries can be recovered through various methods to prevent environmental contamination, and Li can be reused as a recyclable resource. Classical technologies for recovering lithium from batteries are associated with various environmental issues, so lithium recovery remains challenging. However, the emergence of membrane processes has opened new research directions in lithium recovery, offering hope for more efficient and environmentally friendly solutions. These processes can be integrated into current industrial recycling flows, having a high recovery potential and paving the way for a more sustainable future. A second method, biolexivation, is eco-friendly, but this point illustrates significant drawbacks when used on an industrial scale. We discussed toxicity induced by metals associated with Li to iron-oxidizing bacteria, which needs further study since it causes low recycling efficiency. One major environmental problem is the low efficiency of the recovery of Li from the water cycle, which affects global-scale safety. Still, electromembranes can offer promising solutions in the future, but there is needed to update regulations to actual needs for both producing and recycling LIB.
全球对减少污染的关注,以及电子设备技术的持续发展,给锂离子电池的开采、使用以及通过关键金属回收进行回收利用带来了未来挑战。报告了若干人类和环境问题,包括锂废物引起的相关疾病。锂离子电池中的锂可通过各种方法回收以防止环境污染,并且锂可作为可回收资源再利用。从电池中回收锂的传统技术存在各种环境问题,因此锂回收仍然具有挑战性。然而,膜工艺的出现为锂回收开辟了新的研究方向,为更高效和环保的解决方案带来了希望。这些工艺可整合到当前的工业回收流程中,具有很高的回收潜力,为更可持续的未来铺平道路。第二种方法,生物浸出,是环保的,但这一点在工业规模使用时显示出重大缺点。我们讨论了与锂相关的金属对铁氧化细菌的毒性,由于其导致回收效率低,这需要进一步研究。一个主要的环境问题是从水循环中回收锂的效率低,这影响全球安全。尽管如此,电膜未来可以提供有前景的解决方案,但需要根据生产和回收锂离子电池的实际需求更新法规。
