Abstract
A cathode electrode made of metal copper in a neutral or alkaline electrolyte containing hydrogen peroxide, a metal anode having a base electrode potential of copper, and an electric double layer having hydrogen peroxide as a dipole are formed, and a separator-less battery having an insulating dipole electric double layer functioning as a separator between the anode electrode and the cathode electrode and a metal-air battery having a copper cathode having an electric double layer having hydrogen peroxide as a dipole are provided as an air electrode.
Claims6
An air electrode made of a transition metal selected from a group comprising copper and an alloy thereof, used for a metal-air cell comprising a neutral or alkaline electrolytic solution, an air electrode as a cathode, and an electrode as an anode made of a typical metal selected from a group comprising aluminum, zinc, magnesium, and an alloy thereof whose electrode potential is base from the air electrode, wherein the electrolytic solution contains hydrogen peroxide, and wherein the air electrode and the electrolytic solution make an electric double layer containing hydrogen peroxide as a dipole which is formed at an interface between the air electrode and the electrolytic solution.
A metal-air cell comprising a neutral or alkaline electrolytic solution, an air electrode, as a cathode and an electrode as an anode made of a typical metal selected from the group consisting of aluminum, zinc, magnesium, and an alloy thereof, the electrode potential of which is base than that of the air electrode, wherein the electrolytic solution contains hydrogen peroxide, and the air electrode is selected from a group comprising copper and an alloy thereof, wherein an electric double layer containing hydrogen peroxide as a dipole is formed at an interface between the air electrode and the electrolytic solution.
