Abstract:
1. A battery grid comprising: a frame comprising a top element, a bottom element, a first side element, and a second side element; a plurality of wires provided within the frame and defining a plurality of open areas, including a plurality of first linear vertical wire members which radially extend from the top element to the bottom element, a plurality of second linear vertical wire members which extend from the bottom element toward the top element but terminate before reaching the top element creating a subset of open areas, and a plurality of linear horizontal wire members which extend between the first side element and second side element, wherein a portion of the plurality of wires includes at least one of the second linear vertical wire members provided between consecutive first linear vertical wire members, each of the second linear vertical wire members contact a plurality of linear horizontal wire members prior to termination, wherein the subset of open areas is asymmetric across the grid; and a current collection lug extending from the top element in a first direction.
