    • A lead-acid battery electrode plate is manufactured by consecutively supplying a lead or lead alloy sheet; leaving a part in the vicinity of the center of the sheet as a non-expansion portion and expanding both sides like mesh to form a grid body; filling active material paste into the grid body; and cutting the grid body to predetermined dimensions. In the lead-acid battery electrode plate, the non-expansion portion forms a current collector part of the electrode plate along an expansion portion in an up and down direction of the electrode plate. One or more openings are made in a part of the non-expansion portion. A part of the non-expansion portion is projected above the position of an upper margin of the cut expansion portion as a current collector lug part. When the current collector lug part is placed upside, the expansion direction is the width direction of the electrode plate.
    • 通过连续供给铅或铅合金板来制造铅酸蓄电池电极板; 在片材的中心附近留下一部分作为非扩张部分,并且使两侧像网状物一样扩大以形成网格体; 将活性物质浆料填充到网格体内; 并将网格体切割成预定尺寸。 在铅酸电池用电极板中,非膨胀部沿着电极板的上下方向的膨胀部形成电极板的集电体部。 在非膨胀部分的一部分中形成一个或多个开口。 非膨胀部分的一部分作为集电器凸耳部分突出在切割扩展部分的上边缘的位置上方。 当集电体凸块部分被放置在上侧时,膨胀方向是电极板的宽度方向。

    • A sealed lead-acid battery which includes a container accommodating an assembled element. The assembled element has at least one electrochemically formed positive plate having a grid of an antimony-free alloy, wherein the plate is made of porous active material. The assembled element also includes at least one electrochemically formed negative plate having a grid of an antimony-free lead alloy, wherein the plate is made of a porous active material. A separator, having a plurality of projections on one or both side thereof, is inserted between the positive and negative plates. A layer of powder is placed between the positive and negative plates and around the assembled element. The powder is composed of a closely packed powder, which is acid-resistant and hydrophilic, and has gas channels within its interior. The powder is immobilized with an acid-resistant porous layer placed above the powder, wherein the porous layer is permeable to gases and liquids, and impervious to particles of the powder. Sulfuric acid electrolyte is impregnated and retained within the positive and negative plates and the powder layer in a substantially necessary and sufficient amount for charging and discharging the battery.
    • 一种密封铅酸电池,其包括容纳组装元件的容器。 组装元件具有至少一个电化学形成的具有不含锑合金网格的正极板,其中该板由多孔活性材料制成。 组装元件还包括至少一个电化学形成的具有无锑铅合金栅格的负极板,其中该板由多孔活性材料制成。 在正极板和负极板之间插入具有在其一侧或两侧上的多个突起的分离器。 在正极板和负极板之间以及组装的元件周围放置一层粉末。 粉末由紧密堆积的粉末组成,其耐酸性和亲水性,并且在其内部具有气体通道。 该粉末用位于粉末上方的耐酸性多孔层固定,其中多孔层可渗透气体和液体,并且不渗透粉末颗粒。 硫酸电解质浸渍并保持在正极板和负极板和粉末层中,其基本上必需且足够的量用于对电池进行充电和放电。
