摘要： In casting tubular-plate grids, a molten lead alloy is poured into a mold along the long side of the grid perpendicular to the grid rods. Temporary connectors joining adjacent grid rods are simultaneously cast. These connecting portions have a thickened cross-section in the middle and a constricted cross-section at their points of junction with the grid rods. In a subsequent operation, the connecting portions are punched out.

摘要： A flat, long-life alkaline primary cell having a low water content comprises a positive electrode of mercuric oxide or silver oxide, a negative electrode of amalgamated zinc or cadmium, and separator layers disposed between the electrodes. The positive electrode lies upon a disc of nickel screening. Flanged edges of two of the separator layers are gripped between a cover and a sealing ring. The electrolyte absorbed by the separator layers is a mixture of sodium hydroxide, potassium hydroxide, and rubidium hydroxide. The number of moles of water per mole of alkali hydroxide is 2.0-2.7 for sodium hydroxide, 2.4-3.1 for potassium hydroxide, and 2.8-4.0 for rubidium hydroxide.

摘要： This invention relates to an alkaline primary battery of the type having a negative electrode containing cadmium or amalgamated zinc and a positive electrode containing monovalent silver oxide, mercuric oxide, or mixtures of these oxides with manganese dioxide, the positive electrode having an electrochemically active surface area facing the negative electrode. At positive electrodes, self-discharge can be caused by the solubility of the active material. It is an object of this invention to provide an improved alkaline primary battery designed to reduce this type of self-discharge, without impairing the internal resistance of the battery. To this end, in the alkaline primary battery the improvement comprises at least one electrically conductive, microporous, electrolyte-saturated, optically opaque filter-electrode which covers the entire active surface area of the positive electrode, contains either no monovalent silver oxide nor mercuric oxide or only a substantially smaller amount thereof per unit of volume than the positive electrode, contains electrically conductive material which is not corroded, oxidized, nor dissolved in alkali electrolytes at the given potential of the positive electrode, and is in electrical contact with the positive electrode.

摘要： Disposed between the positive electrode and the negative electrode in addition to the separator layer is an electrolyte-impermeable inert film or foil about 5 to 50 microns thick. The film or foil includes a very small current-focusing aperture produced by piercing, punching, or melting. The entire electrolytic current is focused through this aperture. The area of the aperture is at least ten times smaller than the surface area of the separator layer. The thickness l of the film or foil and the radius r.sub.i of the aperture are governed by the relationship 4l/r.sub.i .ltoreq.10. The electrolyte-impermeable film or foil is sealingly clamped between the positive electrode and a sealing ring at the edge of the cell. The film or foil may be of a synthetic resin polymer material, of nickel, or of a nickel alloy. Self-discharge is decreased by the construction of the cell. The cell may be in a flat form without any appreciable decrease in the energy density taking place. Furthermore, the cell presents advantages when electrolytes having a low freezing point are used. The cell is well suited as a power source for electronic watches, pacemakers, or as a voltage source for electronic memories.
摘要翻译：除了隔膜层之外，在正电极和负电极之间设置有约5至50微米厚的电解质不可渗透的惰性膜或箔。膜或箔包括通过穿孔，冲压或熔化而产生的非常小的电流聚焦孔。整个电解电流通过该孔聚焦。孔径的面积比分隔层的表面积小至少十倍。膜或箔的厚度l和孔径的半径ri由关系41l / ri 10决定。电解质不渗透膜或箔密封地夹在正电极和电池边缘处的密封环之间。膜或箔可以是合成树脂聚合物材料，镍或镍合金。自放电由于电池的构造而减少。电池可以是平坦的形式，而不会发生能量密度的明显降低。此外，当使用具有低凝固点的电解质时，电池具有优点。该电池非常适合作为电子手表，起搏器或电子存储器的电压源的电源。
