Battery grid

A grid for a battery comprising:

• a stamped grid network bordered by frame elements, the frame elements including a top frame element, a bottom frame element and a side frame element, the top frame element having a current collector lug;
• the stamped grid network having grid wires with a smooth outer surface and rectangular cross section formed by the stamping process which grid wires are reshaped to have a non-rectangular transverse cross-section, the stamped grid network comprising a plurality of spaced apart grid wire elements joined with a plurality of nodes to define a plurality of open spaces, the open spaces being devoid of structural elements provided in between the grid wire elements, the stamped grid network having a vertical grid wire element extending from the top frame element and parallel to the side frame element forming a radius line running through the vertical grid wire element, and an additional grid wire element extending radially from the top frame element such that it intersects the radius line.

A battery comprising:

• a battery grid comprising a frame having a plurality of frame elements surrounding a grid network formed by stamping, the grid network including reshaped grid wire elements and nodes interconnecting the grid wire elements, the reshaped grid wire elements and nodes having a transverse cross-sectional shape deformation formed by coining of the grid wire elements, the grid network and frame elements define opposed planar surfaces extending from a top frame member to a bottom frame member, each grid wire element being joined to one of the nodes to define a plurality of open spaces, the open spaces having four sides provided through the battery grid perpendicular to the opposing planar surfaces.
