Synergetic interactions improve cobalt leaching from lithium cobalt oxide in microbial fuel cells

- Cobalt leaching from lithium cobalt oxide was successfully achieved in MFCs.
- Synergetic interactions were observed for cobalt leaching in MFCs.
- External resistor, solid/liquid ratio and solution conductivity affected performance.
- A pH of 1.0 and a temperature of 35 °C improved cobalt leaching.
- Apparent activation energy of 30.6 kJ/mol was estimated.
