Synthetic Shewanella-Bacillus Microbial Consortia for Enhanced Metal Oxide Leaching From Spent Lithium-Ion Batteries Using Brewing Wastewater as Leaching Agent. [PDF]
Adv Sci (Weinh)A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.
