| abstract |
The invention relates to an alkaline accumulator for storing electrical energy with a positive electrode, which comprises a nickel foam tape, a nickel tape or nickel-plated perforated or non-perforated steel tape and a pasty active material, which mainly consists of nickel hydroxide and particles of cobalt hydroxide, cobalt monoxide and one, as the carrier material Contains plastic binder, a negative electrode and a separator arranged between the electrodes in a closed housing. The positive active material contains 9 to 20% by weight of a graphite mixture as a conductive agent, which consists of more than 70% of fibrous graphite with a fiber length of 10 to 35 µm and a fiber diameter of 3 to 8 µm, and otherwise of spherical graphite with a particle diameter d 50 consists of 3 to 8 µm. |
