Abstract
The invention relates to an alkaline rechargeable battery for storing electrical energy having a positive electrode which, as the substrate material, has a nickel foam strip, a nickel strip or nickel-plated perforated or unperforated steel strip and a pasty active material, which is composed mainly of nickel hydroxide and contains particles of cobalt hydroxide, cobalt monoxide as well as a plastic binding agent, a negative electrode and a separator which is arranged between the electrodes, in a closed housing. As the conductive agent, the positive active material contains 9 to 20% by weight of a graphite mixture, which is composed of more that 70% of fibrous graphite with a fiber length of 10 to 35 μm and a fiber diameter of 3 to 8 μm, and, in addition to this, spherical graphite with a particle diameter dof 3 to 8 μm.
