Abstract

The invention relates to a reversible manganese dioxide electrode, comprising an electrically conductive carrier material having a nickel surface, a nickel layer made of spherical nickel particles adhering to each other and having an inner pore structure applied to the carrier material, and a manganese dioxide layer applied to the nickel particles, wherein the manganese dioxide layer is also present in the inner pore structure of the nickel particle.The invention also relates to a method for producing such a manganese dioxide electrode, the use thereof in rechargeable alkaline-manganese batteries, and a rechargeable alkaline-manganese battery containing a manganese dioxide electrode according to the invention.
