摘要： An asymmetric, secondary electrochemical cell having an aqueous, alkaline electrolyte includes a negative electrode which as anode storage material includes a carbon-based storage material that allows the storage of electric charge in the electrode by formation of an electric double layer and also an additional storage material that can store electric energy by redox reactions. The positive electrode of the cell includes nickel hydroxide and/or nickel oxyhydroxide and/or a derivative of these nickel compounds as cathode storage material. The capacity of the negative electrode Kn has a ratio X to the capacity of the positive electrode Kp of 0.7:1 to 5:1. The additional storage material is present in a proportion of 0.1 to 8% by weight in the negative electrode, based on the dry weight thereof.
