A paste extruding device for a tubular positive plate includes a plate main body. The plate main body includes a cross beam, ribs and a tab. The ribs are linearly distributed on a bottom surface of the cross beam, and the tab is provide on a top surface of the cross beam. A processing tube is sleeved outside the rib, and the processing tube has a cavity shell structure with an open top. A filling cavity is formed between the rib and the processing tube, and a sliding groove is provided at a vertical central line of an outer wall of the processing tube. A processing sliding base is slidably sleeved on the outer wall of the processing tube. A paste extruding cavity is provided at an inner top of the processing sliding base, and a cooling cavity is provided at an inner bottom of the processing sliding base.

A liquid-type lead storage battery includes a positive electrode collector formed of a lead alloy having a rolled structure. A grid substrate of the collector has an upper frame bone located on the upper side and a lower frame bone located on the lower side, each extending laterally, and a pair of vertical frame bones extending vertically. A lug projects upward from a position shifted to the side close to either one of the pair of vertical frame bones from the longitudinal center of the upper frame bone. The intermediate bones have vertical intermediate bones from the upper to lower frame bone and lateral intermediate bones connecting the pair of vertical frame bones. At least one of the lateral intermediate bones has a cross-sectional area B larger than an average value A of the cross-sectional areas of the plurality of lateral intermediate bones, such that B/A is 1.15 or more.

Battery components are generally provided. In some embodiments, the battery components can be used as pasting paper and/or capacitance layers for batteries, such as lead acid batteries. The battery components described herein may comprise a plurality of fibers. The battery component may include, in some embodiments, a plurality of fibers and, optionally, one or more additives such as conductive carbon and/or activated carbon. In certain embodiments, the plurality of fibers include relatively coarse glass fibers (e.g., having an average diameter of greater than or equal to 2 microns), relatively fine glass fibers (e.g., having an average diameter of less than 2 microns), and/or fibrillated fibers. In some instances, such fibers may be present in amounts such that the battery component has a particular surface area, mean pore size, and/or dry tensile strength.

A connection assembly includes a substrate formed of a non-conductive material, a first current collector disposed on a first side of the substrate, and a second current collector disposed on a second side of the substrate. The substrate has a via extending through the substrate from the first side of the substrate to the second side of the substrate opposite the first side. A connection element is disposed in the via between the first current collector and the second current collector. The connection element mechanically and electrically connects the first current collector and the second current collector through the via.

A battery paste application machine is equipped with a battery paste application hopper assembly. The battery paste application machine can be employed in a larger manufacturing operation to produce lead-acid batteries. The battery paste application hopper assembly furnishes automated control of one or more parameters of battery paste delivery. Volume of battery paste at the time of delivery can be automatically controlled, pressure of battery paste at the time of delivery can be automatically controlled, or both volume and pressure can be automatically controlled. Depending on the parameters controlled, the battery paste application hopper assembly can include a housing, a paste delivery roller, a feed roller, a scraper bar, a first actuator, and/or a second actuator.
