The active substance of the positive electrode of an accumulator cell consists of crystalline and polycrystalline lead superoxide in which the lead has its maximum valency of 4. The polycrystalline lead superoxide is an aggregation of individual crystalline substances which are in different growth and development phases. The active substance is located, as an adhering and permanent coating layer, on a carrier plate consisting of Pb, a Pb-Sb alloy or an inert non-conductor which is coated with a Pb or Pb-Sb alloy. An accumulator cell having such an electrode has reduced internal resistance and higher capacity, and it can be recharged quicker. |
