Abstract:
A grid for a battery comprising:an electrically conductive grid body having opposed top and bottom frame elements and opposed first and second side frame elements; anda plurality of interconnecting electrically conductive grid elements defining a grid pattern defining a plurality of open areas, the interconnecting grid elements includinga plurality of radially extending vertical grid wire elements connected to the top frame element, a first portion of the radially extending vertical grid wire elements being connected to the top frame element and the first side frame element, the first portion of the radially extending vertical grid wire elements including a first innermost vertical grid wire element located furthest from the first side frame element, a second portion of the radially extending vertical grid wire elements being connected to the top frame element and the second side frame element, the second portion of the radially extending vertical grid wire elements including a second innermost vertical grid wire element located furthest from the second side frame element, and a third portion of the radially extending vertical grid wire elements located between the first portion of the radially extending vertical grid wire elements and the second portion of the radially extending vertical grid wire elements, the third portion of the radially extending grid wire elements being connected to the top frame element and the bottom frame element, anda plurality of spaced-apart cross wire grid elements, a first set of the spaced-apart cross wire grid elements extending between the first side frame and the first innermost vertical grid wire element, a second set of the spaced-apart cross wire grid elements extending between the first innermost and the second innermost vertical grid wire elements, and a third set of the spaced-apart cross wire grid elements extending between the second side frame and the second innermost vertical grid wire element,wherein a plurality of the second set of cross wire grid elements are connected to the third portion of the radially extending vertical grid wire elements in a staggered manner so that the plurality of the second set of cross wire grid elements that are connected to the third portion of the radially extended vertical grid elements in a staggered manner are not continuous.
