Description of the Related Art In general, a grid used in a lead-acid battery is composed of a frame 1 having an upper transverse bone 1a and a lower transverse bone 1b, an inner bone 2 and a collecting ear 3 as shown in FIG. ing. The inner bone 2 is composed of a plurality of vertical bars 4 and a plurality of horizontal bars 5 orthogonal to each other. However, the vertical 4
In the conventional grid body in which the horizontal and cross rails 5 are orthogonal, the voltage characteristics and the high-rate discharge characteristics are inferior. Therefore, a grid body capable of improving these characteristics has been studied. For example, 52-4
In the lattice body disclosed in Japanese Patent No. 8632, as shown in FIG.
By providing a vertical bar 6 extending radially from a to the lower horizontal side 1b of the frame bone 1, the characteristics are to be improved. Further, in the lattice body disclosed in Japanese Utility Model Application Laid-Open No. 54-56130, the characteristics are improved by increasing the distribution of the mass in the vicinity of the current collecting ear to the mass of the entire lattice body.

物質の劣化を助長するからである。However, in a lattice body in which a radially extending vertical bar is newly added, the weight of the lattice body is increased, so that there is a problem that the cost of the divisional body is increased. Further, in a grid body in which the mass distribution near the current collecting ears is increased with respect to the entire weight of the grid body, although the voltage characteristics are improved, there is a drawback that the battery life is easily reduced.
This is because the vicinity of the current collecting ear is a place where the active material is greatly deteriorated, and if the mass distribution near the ear is increased, the deterioration of the active material near the ear is promoted.

The upper ends of the plurality of vertical rails are respectively connected to the upper horizontal bones of the frame bone, and do not extend toward the lower horizontal bone side of the frame bone so that the plurality of vertical rails do not cross each other. Then, the mass of the upper horizontal bone of the frame bone is set to 11% or more and 14% or less of the mass of the entire lattice body, and the total mass of the mass of the upper horizontal bone and the masses of the plurality of vertical bars is 60% of the mass of the entire lattice body. The mass is distributed so as to be at least 70%.

が劣化して電池の寿命特性が低下する。In the grid body in which the current is concentrated in the current collecting ear, the electrical loss in the upper horizontal bone of the frame below the current collecting ear and the vertical rail connected to the upper horizontal bone increases. Therefore, the voltage characteristics of the grid body largely depend on the mass distribution of the upper horizontal bone and the vertical rail of the frame bone to the entire grid body, and even if the mass distribution of parts other than the upper horizontal bone and the vertical rail is changed, the grid No significant change is seen in the body's voltage characteristics. Therefore, as a result of various studies, the mass of the upper transverse bone of the frame bone was calculated as 11 to 11 of the mass of the entire lattice body.
When the mass of the grid is distributed so that the mass of the upper transverse bone and the mass of the plurality of vertical beams is 60 to 70% of the mass of the entire grid, the life characteristics of the battery are improved. The inventor has found that If the mass of the upper transverse bone of the frame bone is less than 11% of the mass of the entire lattice, and the combined mass of the mass of the upper transverse bone and the masses of the plurality of vertical beams is less than 60% of the mass of the entire lattice, the mass is collected. The electrical performance is reduced, the mass of the upper transverse bone of the frame bone exceeds 14% of the mass of the entire lattice,
If the combined mass of the upper horizontal bone and the masses of the plurality of vertical bars exceeds 70% of the mass of the entire lattice, the active material near the ears is deteriorated, and the life characteristics of the battery are reduced.
