Abstract
Official abstract text for this publication.
An electrolyte for metal-air batteries, which is able to inhibit the self-discharge of metal-air batteries, and a metal-air battery using the electrolyte. The electrolyte for metal-air batteries having an anode containing at least one kind of metal element selected from aluminum and magnesium, may comprise an aqueous solution comprising a self-discharge inhibitor containing at least one kind of ion selected from the group consisting of an H 2 P 2 O 7 2− anion and a Ca 2+ cation and at least one kind of ion selected from the group consisting of a CH 3 S − anion, an S 2 O 3 2− anion and an SCN − anion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A metal-air battery comprising: an air electrode configured to receive an oxygen supply; an anode containing iron as an impurity and at least one kind of metal element selected from aluminum and magnesium; and an electrolyte in contact with the air electrode and the anode, the electrolyte comprising an aqueous solution comprising a self-discharge inhibitor containing at least one kind of ion selected from the group consisting of an H 2 P 2 O 7 2− anion and a Ca 2+ cation and at least one kind of ion selected from the group consisting of a CH 3 S − anion, an S 2 O 3 2− anion and an SCN − anion. 2. The metal-air battery according to claim 1 , wherein the self-discharge inhibitor comprises at least one selected from the group consisting of Na 2 H 2 P 2 O 7 and Ca(OH) 2 and at least one selected from the group consisting of CH 3 SNa, Na 2 S 2 O 3 and NaSCN. 3. The metal-air battery according to claim 1 , wherein a content of the self-discharge inhibitor is in a range of 0.001 mol/L or more to 0.1 mol/L or less. 4. The metal-air battery according to claim 1 , wherein the aqueous solution is basic. 5. The metal-air battery according to claim 1 , wherein the aqueous solution further comprises NaOH as an electrolyte compound.
