A vanadium redox-flow battery has been developed at UNSW.
The battery consists of several cells connected in series. |
| at cathode reduction | V(OH)4+ + 2H+ + e¯  VO2+ + 3H2O
| Eo = 1.000 V
| at anode | oxidation V2+ | V3+ + e¯
Eo = −0.265 V
|
|
|
| complete | cell V(OH)4+ + V2+ + 2H+ | VO2+ + V3+ + 3H2O
Ecell = 1.256 V
| |
| Note: the cell potential is the electrode potential of the positive electrode  minus the electrode potential of the negative electrode.
