Battery recycling has attracted attention as a solution to maintain the chain of demand and supply. First time, a selective biological process assisted by a neutrophilic microorganism for lithium recovery from Li-FP battery cathodes is exhibited. Thiobacillus thioparus, a biosafety level-1 bacterium is used to selectively leach lithium at near-neutral pH. The study showed the leaching was efficient, selective, and environmentally friendly as it could recover 65–98% lithium, with negligible iron, under different experimental conditions supported solely by bacterial activity. Thereafter, lithium was recovered as Li₃PO₄ from the leach solution, which was subsequently reuse as a culture medium to grow an alkaliphilic bacteria for other applications. The liquid and solid residues were characterized by FAAS, ICP-MS, XRD, FESEM, XPS, UV–visible, and FTIR techniques. The developed process could suggest a sustainable alternative for reclaiming selective recovery of critical metal, which needs to meet the demand for continuous consumption in battery production.

电池回收作为维持供需链的解决方案备受关注。首次展示了一种由嗜中性微生物辅助的选择性生物过程，用于从 Li-FP 电池阴极回收锂。Thiobacillus thioparus是一种生物安全级别为 1 的细菌，用于在近中性 pH 条件下选择性浸出锂。该研究表明，浸出是高效、有选择性且环保的，因为它可以在仅由细菌活动支持的不同实验条件下回收 65-98% 的锂，铁含量可忽略不计。此后，从浸出液中_{以 Li 3} PO ₄的形式回收锂，随后被重新用作培养基来培养用于其他应用的嗜碱细菌。液体和固体残留物通过 FAAS、ICP-MS、 XRD、FESEM、XPS、UV-vision 和 FTIR 技术进行表征。开发的工艺可以为回收关键金属的选择性回收提供可持续的替代方案，这需要满足电池生产中连续消耗的需求。
