Abstract
Official abstract text for this publication.
An iron-zinc battery includes a positive electrode containing iron oxyhydroxide, a negative electrode containing zinc, and an aqueous electrolytic solution disposed between the positive electrode and the negative electrode. The aqueous electrolytic solution contains zinc chloride (ZnCl2), and the weight of the zinc chloride (ZnCl2) is equal to or more than the weight of water (H2O) contained in the aqueous electrolytic solution.
First claim
Opening claim text (preview).
1 . An iron-zinc battery comprising: a positive electrode containing iron oxyhydroxide; a negative electrode containing zinc; and an aqueous electrolytic solution disposed between the positive electrode and the negative electrode, wherein the aqueous electrolytic solution contains zinc chloride (ZnCl 2 ), and a weight of the zinc chloride (ZnCl 2 ) is equal to or more than a weight of water (H 2 O) contained in the aqueous electrolytic solution. 2 . The iron-zinc battery according to claim 1 , wherein the aqueous electrolytic solution is a zinc chloride concentrated electrolytic solution containing 3 mol or less of the water (H 2 O) with respect to 1 mol of the zinc chloride (ZnCl 2 ). 3 . The iron-zinc battery according to claim 1 , wherein the positive electrode and the negative electrode are applied to a sheet-like current collector containing at least one selected from the group consisting of copper, iron, and carbon. 4 . The iron-zinc battery according to claim 1 , having a bipolar type stack structure. 5 . The iron-zinc battery according to claim 2 , wherein the positive electrode and the negative electrode are applied to a sheet-like current collector containing at least one selected from the group consisting of copper, iron, and carbon. 6 . The iron-zinc battery according to claim 2 , having a bipolar type stack structure. 7 . The iron-zinc battery according to claim 3 , having a bipolar type stack structure.
