Stamped battery grid with kinked grid wires

摘要

A grid for a battery having a plurality of spaced apart vertically extending and horizontally extending grid wire elements with each grid wire element having opposed ends joined to one of a plurality of nodes to define a plurality of open spaces and with selected ones of the grid wire elements being joined at one of their ends to frame elements. Oppositely facing sides of the grid wire elements define first and second planes that are parallel to each other. Selected ones of the frame elements have an undulating cross section across the width thereof with an apex of the undulation on one side of the grid being tangential to or terminating at a third plane that is separate from and parallel to the first and second planes.

1. A grid for a battery, comprising:
a grid network bordered by a frame comprising one or more frame elements, one of the frame elements having a current collector lug;
the grid network comprising a plurality of spaced apart vertically extending and horizontally extending grid wire elements, each grid wire element having opposed ends, each opposed end being joined to one of a plurality of nodes to define a plurality of open spaces, selected ones of the grid wire elements being joined at one of their ends to the one or more frame elements, oppositely facing sides of the grid wire elements defining first and second planes that are parallel to each other; wherein selected ones of the horizontally extending grid wire elements have a kink formed therein causing the material of the grid wire element to extend beyond at least one of the respective first and second planes and having an apex on at least one side of the grid wire elements that is tangential to or terminating at a third plane but does not extend beyond the third plane; wherein the kinks are positioned on the horizontally extending grid wire elements between neighboring open spaces of the plurality of open spaces; wherein selected ones of the horizontally extending grid wire elements are planar; wherein at least one of the horizontally extending grid wire elements is parallel with the one frame element that has the collector lug.
