锂离子电池（LIB）的大规模回收对于满足全球对实施该技术所需的原材料需求至关重要，这是清洁能源战略的一部分。然而，尽管这正迅速成为一个关键的需求，一个有效的和可持续的回收过程的锂离子电池尚未开发。生物反应在温和的条件下具有很大的选择性，为实施更具环境可持续性的工艺提供了新的途径。在这里，我们展示了一个连续的过程，采用两种细菌物种回收锰，钴和镍，从车辆LIB通过生物合成的金属纳米粒子，而锂仍然在浸出液。此外，在30 L生物反应器中以半中试规模证明了从多金属溶液中回收Mn的可行性。此外，为了深入了解发生的生物过程，我们使用蛋白质组学研究了Co和Ni之间的选择性，以确定生物反应，并确认基于生物的方法分离这两种必需金属的潜力。我们的方法确定了实用的生物分离和回收系统的原则和第一步，强调了利用生物特异性对关键材料进行回收和升级循环的相关性。利用细菌过程选择性分离废旧锂离子电池中的战略和关键金属。
The large scale recycling of lithium ion batteries (LIBs) is essential to satisfy global demands for the raw materials required to implement this technology as part of a clean energy strategy. However, despite what is rapidly becoming a critical need, an efficient and sustainable recycling process for LIBs has yet to be developed. Biological reactions occur with great selectivity under mild conditions, offering new avenues for the implementation of more environmentally sustainable processes. Here, we demonstrate a sequential process employing two bacterial species to recover Mn, Co and Ni, from vehicular LIBs through the biosynthesis of metallic nanoparticles, whilst Li remains within the leachate. Moreover the feasibility of Mn recovery from polymetallic solutions was demonstrated at semi-pilot scale in a 30 L bioreactor. Additionally, to provide insight into the biological process occurring, we investigated selectivity between Co and Ni using proteomics to identify the biological response and confirm the potential of a bio-based method to separate these two essential metals. Our approach determines the principles and first steps of a practical bio-separation and recovery system, underlining the relevance of harnessing biological specificity for recycling and up-cycling critical materials. Harnessing bacterial processes for the selective separation of strategic and critical metals contained in spent lithium-ion batteries (LIBs).
