| Popis: | Studies on the addition of a conducting component (carbon black, graphite, carbonyl nickel) and poly(tetrafluoroethylene) as binder to the active material used in pocket-type nickel oxide electrodes have shown that the second discharge step, which is observed in the discharge curve of a pressed nickel oxide electrode in the potential range from −100 to −600 mV (Hg/HgO), can be markedly influenced or fully suppressed as in the case of a sintered nickel oxide electrode. The existence of this discharge step is attributed to differences in the ohmic contacts of the electroactive particles in the pressed electrode. |
