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.

An electrolyte glass for use as the solid electrolyte in high-temperature galvanic batteries, for example a sodium-sulfur battery. The glass electrolyte has relatively low resistivity and high corrosion resistance and is easily worked by glass manufacturing techniques. The composition of the glass electrolyte according to the invention is defined by xNa.sub.2 O.multidot.ySiO.sub.2 .multidot.zAl.sub.2 O.sub.3.

The heat transfer in a nickel-oxide/hydrogen battery cell is substantially improved by increasing the thermal conductivity in the axial direction of the electrode stack. This improvement in thermal conductivity is due principally to the construction of the negative electrode containing catalyst as an integral part of the gas diffusion element, thus reducing the number of components in an electrode unit of the battery stack from six to four.

Nickel-oxide/hydrogen battery cells

Nickel/hydrogen cells have a long cycle life and other attributes making them desirable for electric vehicle applications, but their cost is high. Cost reduction is obtained by the use of positive electrodes with high capacity per unit area, e.g. porous sintered nickel oxide electrodes, which contain absorbed therein major quantities of the electrolyte. The structure of positive and hydrophilic negative electrodes and of separators is specially adapted for this purpose.
