ABSTRACT:
A storage battery cell based on the principle of the oxygen cycle, having a block-shaped, gastightly sealed cell housing in which the rectangular electrode plates of different polarity are stacked. The electrode plates are electrically connected via current collector lugs to positive and negative terminal pillars of corresponding polarity passed through the wall of the same housing side. In order to achieve a longer service life of the cell, the electrode plates are arranged in parallel with the housing wall of the terminal pillars and are enclosed in an equidistant manner on all four peripheral sides of the electrode plates by the walls of the cell housing. All the electrode plates have in each case a central hole on whose inner edge the current collector lugs are mounted, the current collector lugs being routed elastically in the duct formed by the central holes to the terminal pillars of the corresponding polarity. A uniform pressure can be exerted on the electrode stack by means of an area covering arrangement of spring elements. The separators project at least at the outer edge, the edges all being bent axially in the same direction and overlapping in a scale-like manner.
