A method of assembling a bipolar lead-acid battery includes assembling the electrochemical components necessary to provide the necessary voltage and capacity, maintaining the electrochemical components under the desired compression and then sealing such electrochemical components as a unit utilizing various assembly components. The resulting bipolar battery in the preferred embodiment includes an electrolyte fill/vent box that seals the top of the electrochemical component unit and a vacuum box that seals the bottom surface.

An assembly for a recessible carrying handle is provided for a battery having a container and cover. The assembly comprises: an elongated recess in the top surface of the cover; an elongated recess in opposing side wall surfaces of the cover, which cover side recesses communicate with the ends of the cover top recess; an elongated recess in opposing side wall surfaces of the container, which container side recesses communicate with the cover side recesses; a pair of tongues projecting from the side walls of and into each container side recess; a generally U-shaped handle having two limbs connected by a cross piece; a pair of grooves in the sides of each handle limb, which grooves are adapted to slidably receive the tongues; and a pair of slots in the grooves, which slots are adapted to allow passage of the tongues in and out of the grooves;whereby the handle may be attached readily and without significant distortion to an otherwise completely assembled battery and upon attachment is slidably received in the recesses.

A multi-cell, lead-acid electric storage battery of the wet or absorbed electrolyte type is provided. The battery comprises one or more manifolding apertures in one or more partition walls, which apertures are of a size which allows passage of gases and in wet batteries minimizes passage of electrolyte and which define one or more sets of manifolded cells; a single trapping chamber associated with each set of manifolded cells; one or more vent apertures for wet battery applications or a pressure release valve for absorbed electrolyte battery applications is disposed between each set of manifolded cells and its respective trapping chamber, which vent apertures are of a size which allows passage of gases and in wet batteries minimizes passage of electrolyte. Additionally, for wet batteries there is provided one or more drain/vent apertures between each set of manifolded cells and its respective trapping chamber, which drain apertures are of a size which allow drainage of electrolyte from the trapping chamber to the manifolded cells and minimize passage of electrolyte from the cells to the trapping chamber and a single exhaust port associated with each of said trapping chambers, which exhaust ports allow passage of gas from the trapping chambers to the ambient. Also, battery spacers are provided to make the batteries compatible with mounting devices for larger batteries, and/or to make the batteries stackable.

A method for making a plurality of lead-acid cells requiring a constant width, a height varying from a maximum to a minimum to accommodate plates of varying height and a cell depth to accommodate a minimum to a maximum number of plates is disclosed which utilizes blow molding to form a jar precursor which is cut to the height desired, and, in its preferred aspects, including use of a mold and insert sets which simplify tooling and change-over time, as well as a cover and jar design which simplifies the heat sealing of these components.
摘要:
A method of making lead-acid cell-to-cell or battery-to-battery connections is disclosed which utilizes a non-conductive capture mold, made, for example, from polypropylene polymers, which capture mold has a base having holes allowing the capture mold to be placed over adjacent terminal posts of like polarity and upstanding walls having a height equal to that of the terminal posts, the capture mold serving to retain the lead alloy connector in place while the cell or battery connection is made, as by induction heating or the like.
摘要:
A method and apparatus for more efficiently fusing the straps of pre-formed terminal post members with plate lugs of a battery plate group utilizing a non-reusable, inexpensive plastic mold insert. The method includes positioning the battery plate group into an open top container with the lugs of the positive plates in one row and the lugs of the negative plates in another row, positioning the plastic insert into the container with the lugs of the plate group extending upwardly through the mold insert, positioning the terminal post members on the plastic mold insert with fingers of the straps thereof disposed between plate lugs of the respective rows, supplying additional unmelted lead into remaining spaces between the plate lugs, and heating, melting, and fusing the plate lugs, strap fingers, and added lead by induction heating to form interconnections between the positive and negative plates in the respective terminals.

A method for making a family of lead-acid cells requiring a constant width, a height varying from a maximum to a minimum to accommodate plates of varying height and a cell depth to accommodate a minimum to a maximum number of plates is disclosed which utilizes blow molding to form a jar precursor which is cut to the height desired, and, in its preferred aspects, including use of a mold and insert sets which simplify tooling and change-over time, as well as a cover and jar design which simplifies the heat sealing of these components.
摘要:
An improved method of bonding battery cell terminal posts to cover bushings is disclosed. The battery cell terminal posts are made of lead alloy material and the cover bushings are made of solder alloy material having a significantly lower melting point than the terminal posts. The bushings are bonded to the terminal posts by heating the terminal posts and bushings to a temperature above the melting point of the material of the bushing, but below the melting point of the material of the post, to effect a secure and leak proof connection without melting of the terminal posts and with lesser chance for damage to the plastic cover. The plastic cover further includes integrally formed annular mold sections in the form of upstanding bosses which completely surround respective bushings and posts.
