摘要:
A process and apparatus for the manufacture of plates of an electrical storage battery involves the partial or total severing of a plate blank from a strip of stock material and the subsequent filling of a grid of the plate blank with a material in paste form prior to the removal of the filled plate from the stock material.

A grid base plate and its method of manufacture comprising intermittently conveying a thin elongated metallic sheet longitudinally in one direction through successive first, second and third stations, the sheet being stopped in each of the stations between successive conveying steps. In the first station, the sheet is bent to form a peripheral upwardly projecting portion in a frame region surrounding an inner grid region. In the second station, a plurality of openings are punched in the grid region and in the third station, the sheet is punched along an outer peripheral edge surface to separate the base plate from the sheet. The upwardly projecting portion forms a space with the grid region which is filled with an active material of a thickness determined by the height of the upwardly projecting portion. The upwardly projecting portion has an outer bend region with an end surface constituting a peripheral edge of the frame which faces laterally outwards and is disposed vertically. The outer bend region has a lower surface disposed in the same horizontal plane as a lower surface of an inner region in the vicinity of the juncture of the projecting portion and the grid region. Thereby, when the base plate is placed on a horizontal planar surface, the peripheral frame region will rest on the horizontal surface along two lines of contact respectively at the bottom of the edge surface and at the lower surface at the juncture of the frame region and the grid region.

This invention relates to a method of producing a paste-type electrode for a lead storage battery which comprises packing into an active material support a paste prepared by kneading a lead oxide having a conversion ratio to red lead (Pb.sub.3 O.sub.4) of 90% or less or a mixture of this lead oxide powder with water and sulfuric acid as the principal components. Because this lead oxide contains red lead less than 90%, red lead formed on the surface of this oxide and lead oxide (PbO) formed in the particle core are directly bonded. This enhances the bonding power between the active materials. The paste-type electrode prepared by this method provides high adhesion of the paste to the active material support and high bonding power between the active materials. Therefore, both improvements in life and in efficiency of formation charge can be attained.

A storage battery including a container and a cover. The container is partitioned into a plurality of cell chambers by a plurality of partition walls. Each cell chamber has a cell therein which is composed of positive and negative plates. The negative and positive plates are connected by negative and positive straps, respectively. An intercell connecting conductor connects negative and positive straps from adjacent cells through an opening in the partition wall. Each intercell connecting conductor includes a horizontal base attached to one of the straps, and an ear which extends obliquely upwardly from the base to the opening in the partition wall. The opening in the partition wall and the ear are laterally offset from the base so that they are vertically unaligned with the base. As a result, the forward tip of a welding gun used to weld two ears from adjacent cells together through the opening in the partition wall will not contact the base even when the height of the ear is of a height that would otherwise permit such contact between the welding gun and the base. The battery also includes positive and negative terminals. The walls of the container and the cover surrounding these terminals are lower than the upper edge of the nearest partition wall directly above the opening. Consequently, the terminals can have a reduced height compared to conventional storage batteries, thereby resulting in less resistance and a higher output, as well as a cheaper cost and a lower height.

A terminal structure for a storage battery in which a plate terminal 1 includes one end plate portion 1a connected to the electrode pole H of the storage battery, and a led-out plate portion 1b led out from the electrode pole H to a notch D of a cover C. The led-out plate portion 1b is formed into a horizontal plate portion 1b1 having a bolt insertion hole 3, and a vertical plate portion 1b2 vertically bent downwards into an L-shape and having a bolt insertion hole 4; and the plate terminal 1 is mounted on a cover face d1 by the vertical plate portion 1b2; characterized in that a lower-plate portion 6 of the vertical plate portion 1b2 is provided with engagement portions 7, 7 and is pressed into a snug fit hole 8 provided in the cover C, so as to fix the respective engagement portions 7, 7 in engagement with opposing inner wall faces 8a, 8b.
摘要:
A cover apparatus in a monoblock storage battery of the type in which the underside surface of the battery cover is provided with cell partition walls for defining a plurality of cell chambers. The underside surface of the cover is further provided with mutually facing walls crossing transversely the cell partition walls and a cover wall on the lower surface thereof which defines an exhaust passage duct common to the plurality of cell chambers which permits the escape of gas generated in the cell chambers while effectively preventing leakage of electrolyte from the battery during gas venting.

A splash-proof device for use in a storage battery is a cylindrical member which is provided interiorly with a helical splash-proof baffle for purpose of preventing a liquid spray from being leaked out of an electrolytic cell, and is provided integrally with an electrolytic cell cover. Since a gas escape passage formed in the splash-proof device is made helical, the condensation effect of the liquid spray and the liquid spray leakage-proof effect are both prominent.
