Functional exploration of extracellular polymeric substances (EPS) in the bioleaching of obsolete electric vehicle LiNixCoyMn1-x-yO2 Li-ion batteries

•Strong adhesion of cells to the spent EV LIBs occurs, mediated by added EPS.•EPS produce aggregates with higher hydrophilicity/surface energy to favour bioleaching.•EPS adsorb both Fe3+ and Fe2+ to concentrate the Fe2+/Fe3+ cycle inside the aggregate.•EPS raise the potential and lower the resistanc...
