✦ Synopsis
Geometric structure measurements of positive electrodes have been determined by measuring cumulative pore vohune, pore size distribution, porosity, pore specific surface area and BET specific surface area. The influence of technological parameters such as concentration of SO1*-ions in the paste, the temperature of the paste and the quality of oxides on the structure of porous positive electrode have been studied. The relation between BET specific surface area and the electricai capacity of the positive electrode is shown and interpreted.

Zusammenfassrmg-Die geometrische Struktur der positiven Platte wurde durch die Bestimmung des Totalporenraumes, der Verteilung der Porenweite, der PorositPt, der spezifischen Porenoberil&che sowie der BET-Oberfl%che ausgemessen. Der Etiuss technologischer Parameter wie die SO,*-Ionen-Konzentration in der Paste, ihre Temperatur, die PulverqualitW auf die Porenstruktur der positiven Platte wurde untersucht. Auch die Beziehung zwischen der BET-OberJ32che und der elektrischen KapazitLt der positiven Platte wurde bestimmt.
