Abstract
A method for the manufacture of lead-acid batteries and associated apparatus and a lead-acid battery design resulting therefrom is disclosed. The method involves providing a battery grid and pasting the grid with a battery paste such that a profiled and tapered battery plate is formed. This battery plate is wrapped onto a coil and cured in curing apparatus. A battery element is formed using coils of the finished plate stock, separator material, and winged end plate. After this, several battery elements are then placed into a battery container.
Claims23
A method of producing a coil of battery plate strip having a single polarity for making lead-acid batteries comprising the steps of
- providing a battery grid strip with a reticulated grid strip portion having first and second sides, and first and second edges,
- passing said battery grid strip through a battery grid pasting station,
- placing a layer of material on said second side of said battery grid strip,
- applying battery paste to said battery grid strip to overpaste said first side of said battery grid strip,
- placing a second layer of material on said first side of said battery grid strip on top of said battery paste,
- forcing a portion of said battery paste through said reticulated grid strip portion to overpaste said second side, whereby both sides of said battery plate strip are overpasted,
- effecting said forcing of said battery paste through said reticulated grid strip portion by paste moving means, and
- coiling said single polarity battery plate strip.
A method of coiling pasted battery stock having a single polarity comprising the steps of
- providing a strip of pasted battery plate stock having a single polarity comprising of a battery grid strip including a reticulated grid strip portion, a lug strip portion on one side of said reticulated grid strip portion and a border strip portion adjacent to said reticulated grid strip portion on an opposite side of said reticulated grid strip portion from said lug strip portion and a battery grid paste layer disposed on said reticulated grid strip portion, and
- wrapping said strip of pasted battery plate stock having a single polarity into a coil, whereby a space is maintained between adjacent wraps of said single polarity pasted battery plate stock.
