Reversible manganese dioxide electrode, method for the production thereof, the use thereof, and rechargeable alkaline-manganese battery containing said electrode

A reversible manganese dioxide electrode, comprising:

• an electrically conductive carrier material;
• a nickel layer formed on the electrically conductive carrier material, the nickel layer comprising spherical nickel particles adhered to one another, the nickel layer having an inner pore structure;
• and
• a manganese dioxide layer formed on the nickel layer and at least partially filling the inner pore structure thereof.

A rechargeable alkaline-manganese battery, comprising:

• a current collector;
• a reversible manganese dioxide electrode surrounding the current collector, wherein the reversible manganese dioxide electrode comprises:
• an electrically conductive carrier material;
• a nickel layer formed on the electrically conductive carrier material, the nickel layer comprising spherical nickel particles adhered to one another, the nickel layer having an inner pore structure;
• and
• a manganese dioxide layer formed on the nickel layer and at least partially filling the inner pore structure thereof;
• a separator layer;
• and
• a negative electrode, wherein the separator layer is sandwiched between the negative electrode and the reversible manganese dioxide electrode.
