Providing is a battery comprising an iron anode, a nickel cathode, and an electrolyte comprised of sodium hydroxide, lithium hydroxide and a soluble metal sulfide. In one embodiment the concentration of sodium hydroxide in the electrolyte ranges from 6.0 M to 7.5 M, the amount of lithium hydroxide present in the electrolyte ranges from 0.5 to 2.0 M, and the amount of metal sulfide present in the electrolyte ranges from 1-2% by weight.

Electrolyte for a nickel-iron battery

The present invention provides one with a Ni&#x2014;Fe battery exhibiting enhanced power characteristics. The battery uses a particular electrolyte. The resulting characteristics of specific power and power density are much improved over conventional Ni&#x2014;Fe batteries. The electrolyte comprises sodium hydroxide, with lithium hydroxide and sodium sulfide. The iron anode comprises an iron active material and a polyvinyl alcohol binder.

Nickel-iron battery with high power

Nickel-iron battery with high cycle life

Provided is an iron based electrode comprising a single layer of a conductive substrate coated on at least one side with a coating comprising an iron active material and a binder. The iron based electrode is useful in a Ni&#x2014;Fe battery as the anode. The electrode can also be prepared by continuously coating each side of the substrate with a coating mixture comprising the iron active material and binder.

Coated iron electrode and method of making same

Provided is a battery comprising an iron electrode and an electrolyte comprised of sodium hydroxide, lithium hydroxide and a soluble metal sulfide. In one embodiment, the concentration of sodium hydroxide in the electrolyte ranges from 6.0 M to 7.5 M, the amount of lithium hydroxide present in the electrolyte ranges from 0.5 M to 2.0 M, and the amount of metal sulfide present in the electrolyte ranges from 1 to 2% by weight.

Electrolyte for battery containing an iron electrode

The present invention provides one with a high cycle life Ni&#x2014;Fe battery. The battery uses a particular electrolyte. The electrolyte comprises sodium hydroxide, as well as lithium hydroxide and sulfide. The use of the sodium hydroxide based electrolyte with the iron anode in the battery has been found to enhance the performance characteristics of the battery. The resulting characteristics of cycle life, as well as power and charge retention, are much improved over conventional Ni&#x2014;Fe batteries.

Provided is a Ni&#x2014;Fe battery comprising an iron electrode which is preconditioned prior to any charge-discharge cycle. The preconditioned iron electrode used in the Ni&#x2014;Fe battery is prepared by first fabricating an electrode comprising an iron active material, and then treating the surface of the electrode with an oxidant to thereby create an oxidized surface.

Nickel-iron battery with a chemically pre-formed (CPF) iron negative electrode

Provided is a process for preparing an electrode comprising an iron active material. The process comprises first fabricating an electrode comprising an iron active material, and then treating the surface of the electrode with an oxidant to thereby create an oxidized surface. The resulting iron electrode is preconditioned prior to any charge-discharge cycle to have the assessable surface of the iron active material in the same oxidation state as in discharged iron negative electrodes active material.

Accelerated formation and increased performance in chemically pre-formed (CPF) iron negative electrodes

Provided is a process for preparing an electrode comprising an iron active material. The process comprises first fabricating an electrode comprising an iron active material, and then treating the electrode with a gaseous oxidant to thereby create an oxidized surface. The resulting iron electrode is preconditioned prior to any charge-discharge cycle to have the assessable surface of the iron active material in the same oxidation state as in discharged iron negative electrodes active material.
