Embodiment Construction

[0038] Next, one embodiment of the battery grid of the present invention will be described with reference to the drawings. In addition, in this embodiment, the grid used for a lead acid battery is demonstrated as an example. Additionally, the figure 1 as well as figure 2 The up, down, left, and right directions on the paper are kept unchanged and described as the up, down, left, and right directions.

[0039] The grid 1 of the present embodiment is used as one member of a positive electrode plate or a negative electrode plate in an electrode group which is a power generation element of a lead acid battery. In addition, when this grid 1 is used for a positive electrode plate, the grid 1 is filled with a positive electrode active material (lead dioxide). On the other hand, when the grid 1 is used for a negative electrode plate, the grid 1 is filled with a negative electrode active material (spongy lead).

[0040]Specifically, the grid 1 is a part obtained by stamping a roll...

Abstract

To regularize a potential distribution of a grid, prevent local corrosion and prolong product lifetime, a storage battery grid includes frame skeleton (2) in a rectangular shape, a lug portion (21) formed upward from an upper side (2a) of the frame skeleton (2), one or more of main vertical skeletons (3X) extending downward from the lug portion (21) in the frame skeleton (2); and a plurality of diagonal skeletons (4) that branch from at least the main vertical skeletons (3X) extending to both sides with the main vertical skeletons (3X) as axes, and that extend diagonally from the upper side (2a) to the lower side (2b). The plurality of diagonal skeletons (4) are disposed at intervals in a direction of extension of the main vertical skeletons (3X), and at least partial of the plurality of spaces demarcated with the main vertical skeletons (3X) as a portion of the sides are in a substantially quadrilateral shape.

Description

technical field [0001] The present invention relates to a battery grid, a method for manufacturing the battery grid, and a battery using the battery grid. Background technique [0002] Conventionally, as a grid used for a storage battery, an ekispand grid (mesh grid) obtained by forming slits in a lead alloy sheet, for example, in a zigzag shape and stretching it, as disclosed in Patent Document 1, has been used. The expanded grid includes: an upper frame formed with ears; a lower frame opposite to the upper frame; and mesh ribs formed between the upper frame and the lower frame. Furthermore, the electrode plate is constituted by filling the squares formed by the upper frame, the lower frame, and the mesh ribs with an active material. [0003] However, since the expanded grid does not have frames connecting the upper frame and the lower frame on the left and right sides, it is easy to elongate in the height direction, and because it is easy to bend and deform in the plane d...
