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.

Abstract: A lead acid cell having unitized positive and negative electrodes positioned within a container such that the respective edges of the positive electrode are spaced apart from the edges of negative electrode. The electrodes are each made up of at least one plate having a major surface with a composition thereon for imparting a negative or positive polarity. The plates of each electrode have first and second edges in which the second edges are connected to an associated current collector and the first edges of each electrode oppose each other in spaced apart relation.

Abstract: A process for dimpling the surface of a pasted Pb-acid storage battery relocates active material from the centers of the active material pellets to the sides thereof more proximate the surrounding grid wires with a consequent increase in surface area of the plate and utilization efficiency of the active material.

Abstract: An electric storage battery including plates of one polarity sheathed in envelopes of separator material wherein each envelope includes a pouch for supporting the distal end of an adjacent opposite polarity plate.

Abstract: A multi cell electric storage battery having an intercell connector manifold sealed within a recess in the battery's cover. The manifold comprises a plurality of conductive lightweight links integral with a nonconductive carrier plate and secured to posts projecting from the battery's cell elements.

Abstract: A pasted Pb-acid storage battery plate having a plurality of dimples formed in the surface(s) of the plate in the center of the grid openings defined by the grid wires. A dimpling process relocates active material from the centers of the active material pellets to the sides thereof more proximate the surrounding grid wires with a consequent increase in surface area and active material utilization efficiency.

Abstract: The output voltage of an engine-driven generator is varied in accordance with engine vacuum in a manner to increase the charging rate during deceleration of the vehicle and to decrease the charging rate during acceleration of the vehicle. The charging current developed in the generator is alternately applied to one or the other of two storage batteries while the other storage battery is connected to supply power to the various electrical loads of the vehicle. A switching circuit responsive to the terminal voltage of the battery connected to supply power to the loads operates to exchange the battery connections when the voltage supplied to the loads decreases below a reference value so that the depleted battery is connected to be charged by the generator and the charged battery is connected to supply power to the loads.

Abstract: A process for coil-curing Pb-acid storage battery plates including the steps of: transversely scoring a length of pasted grid stock to provide a plurality of closely spaced grooves; coiling the pasted stock on to reels; curing and drying the coiled stock; uncoiling the dried stock; and cutting the dried stock into individual battery plates. The grooves control the formation of any cracks formed in the dried paste during uncoiling. A scoring belt permits scoring the stock by molding the grooves therein at the time of pasting.

Abstract: An electric storage battery having an electrochemically active cell element comprising juxtaposed positive and negative polarity electrode plates each at least partially encased in a sheath of microporous dendrite-suppressing battery separator material. Each of the sheaths is sealed along three of its peripheral borders and open on the fourth. The several plates are arranged in the cell element such that the opening in the sheaths for the positive plates face a direction opposite to the direction faced by the openings in the sheaths for the negative plates and such that the sheaths on adjacent plates overlap in the region between adjacent plates.

Abstract: Coining as-cast, Pb-Ca, expanded lead grids destined for use in positive, Faure-type, lead-acid storage battery plates. Expanded, as-cast, Pb-Ca strip is coined to remove all sharp edges and corners, to reorient the alloy's grain boundaries and to submerge nodal expansion cracks for increasing the cycle life of positive Pb-acid storage battery plates made therefrom.
