文摘
- •
Bioleaching efficiently released Li and Mn from EV LIBs, but poor with Co and Ni.
- •
pH adjustment evidently improved bioleaching performance, especially Co and Ni.
- •
Li release was due to solution by biogenic H2SO4 based on indirect mechanism.
- •
Release of Co, Mn, Ni was due to co-work of Fe2+ reduction and acid dissolution.
- •
Direct contact between cathodes and cells was needed for release of Co, Ni and Mn.
