| titleOfInvention | Mixed type zinc-nickel flow battery |
| abstract | A mixed zinc-nickel flow battery comprises a NiO electrode as an anode, a carbon felt or/and a zinc electrode as a cathode, an alkaline solution of ferricyanide ions as an electrolyte of the anode, and an alkaline solution of zinc ions as an electrolyte of the cathode; during charging, the oxidation reaction from ferricyanide ions to ferricyanide ions occurs on the positive electrode, and NiO gradually participates in the electrochemical flow reaction along with the consumption of the ferricyanide ions to generate NiOOH; the negative pole has deposition reaction of zinc ions; during discharging, the anode firstly generates an oxidation reaction from NiOOH to NiO, and iron cyanide ions gradually participate in an electrochemical flow reaction along with the consumption of NiOOH to generate ferrous cyanide ions; and (4) carrying out dissolution reaction on the zinc simple substance of the negative electrode. The invention aims to provide a mixed zinc-nickel flow battery aiming at the problem of limited positive electrode surface capacity of the zinc-nickel flow battery, which is used for improving the energy storage capacity of the zinc-nickel flow battery, and meanwhile, the addition of ferricyanide ions can improve the cycle stability of the positive electrode of the zinc-nickel flow battery. |
