Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 - 18 . (canceled) 19 . A battery comprising an iron anode, a nickel cathode, and an electrolyte comprised of sodium hydroxide, lithium hydroxide and a soluble metal sulfide, wherein the amount of sulfide contained in the electrolyte ranges from 0.23% to 0.75% by weight of the electrolyte, and with the iron anode comprising a polyvinyl alcohol binder. 20 . The battery of claim 19 , wherein the metal sulfide is an alkali metal sulfide. 21 . The battery of claim 20 , wherein the metal sulfide is sodium sulfide. 22 . The battery of claim 19 , wherein the iron anode contains sulfur or sulfur compounds. 23 . The battery of claim 19 , wherein the concentration of sodium hydroxide in the electrolyte is in the range of from 6.0 M to 7.5 M. 24 . The battery of claim 19 , wherein the iron electrode is affixed to a two dimensional conductive substrate. 25 . The battery of claim 24 , wherein the conductive substrate is a perforated strip or expanded metal. 26 . The battery of claim 19 , wherein the iron electrode comprises a three dimensional conductive substrate. 27 . The battery of claim 26 , wherein the conductive substrate is a metal foam, metal felt, or metal foil. 28 . The battery of claim 27 , wherein the foil is a perforated foil in which the perforation result in burrs that protrude above and below the surface of the foil. 29 . The battery of claim 27 , wherein the foil has metallic nickel or iron particles sintered onto the surface of the foil.
