  "textContent": "Nickel/metal hydride secondary element comprises a positive nickel hydroxide electrode, a negative electrode containing a hydrogen storage alloy, and an alkaline electrolyte. The positive electrode provided with a three-dimensional metallic conducting structure contains an aluminum compound soluble in the electrolyte as well as the nickel hydroxide and cobalt oxide. Preferred Features: The aluminum compound is aluminum hydroxide and/or aluminum oxide in an amount of 0.5-1.0 wt.%. The positive electrode contains further oxidic compounds selected from lanthanoids, Y2O3, La2O3 and Ca(OH)2 and their mixtures.",
