    摘要： A lead-acid battery construction includes gridless reactively limited positive and negative electrode means combined with separator material and an electrolyte. Reactive limitation of the negative electrode means may be realized by providing the negative electrode means with inner portions comprising non-reactive (i.e. solid) lead and outer portions of reactive (i.e. porous) lead. Reactive limitation of the positive electrode means may be provided by the said negative electrode means. The positive electrode means comprises PbO.sub.2 which occurs in outer reacting portions and inner non-reacting portions. The battery having such reactively limited electrode means may only be discharged to the extent that the inner reactive lead portions of the negative electrode means become completely transformed into PbSO.sub.4, whereupon all electrochemical reaction in the battery will cease. That portion of the PbO.sub.2 of the positive electrode means which has not been transformed into PbSO.sub.4 may be defined as the non-reacting portion. The electrode means as described above are further characterized by the non-reactive lead portions of the negative electrode means and the non-reacting portions of the positive electrode means being of sufficient mass to carry all required electrical current, both during charging and discharging of the battery. Thereby it becomes possible to provide a battery having gridless electrode means.

    摘要翻译： 铅酸电池结构包括无电极限制的正极和负极装置与隔板材料和电解质结合。 负极装置的无限制限制可以通过提供负极装置的内部部分来实现，该内部部分包括非反应性（即固体）引线和反应性（即多孔）引线的外部部分。 所述负极装置可以提供正极装置的无功限制。 正极装置包括发生在外部反应部分和内部非反应部分中的PbO 2。 具有这种反应性有限的电极装置的电池只能被排出到负极装置的内部反应性引线部分完全转变成PbSO 4的程度，于是电池中的所有电化学反应将停止。 未转化为PbSO 4的正电极装置的PbO 2部分可以被定义为非反应部分。 如上所述的电极装置的特征还在于，负极装置的非反应性引线部分和正极装置的非反应部分具有足够的质量以承载所有所需的电流，在充电和放电期间 电池。 由此，可以提供具有无栅电极装置的电池。

    摘要： The invention relates to a method for producing electrodes (14) for lead-acid batteries (30). An electrode (14) that has been produced comprises at least one upper and/or one lower frame element as well as a lattice-shaped region (12) that extends away from said upper or lower frame element (9, 10) and has a plurality of openings, the upper and/or lower frame element (9, 10) being of a greater thickness (D) than the lattice-shaped region (12). Said method comprises the steps of: a) producing a profiled strip-shaped blank (2) using a casting method in which the strip-shaped blank (2) is formed, solely by means of said casting method, to have a greater thickness (D) on one side in at least one of the regions (3, 5, 7) which should eventually form the upper or lower frame element (9, 10), than the thickness in regions (4, 6) which should eventually form the lattice-shaped region (12), and b) producing said lattice-shaped region (12) with the openings in a subsequent expanded metal process. The invention also relates to an installation for producing electrodes for lead-acid batteries, an electrode, and a lead-acid battery.
