エキスパンド加工したメツシュが用いられている。Conventional technology and its problems Lead alloys are generally used for the grids of lead-acid batteries, but
Its electrical resistance is 21 x 10-6 ohms, which is quite high among metals. Therefore, in large-sized batteries and small-sized batteries that require large current discharge, that is, high-output lead-acid batteries, there are examples in which copper or a copper alloy is used for the negative electrode grid. Incidentally, the electrical resistance of copper is 1.7 x 10-60, which is less than 1/10 that of lead. However, since copper has a higher melting point than lead and is difficult to cast, a mesh formed by expanding a sheet is used.

いという現象である。Problems when using a mesh made of copper material as a grid include electrical and mechanical bonding to the straps or balls and expansion and contraction of the mesh in the expanding direction. In the former method, the edges of the mesh are conventionally embedded in lead or lead alloy bars, but because the contact area between the mesh surface and the lead bar is small, oxides and voids on the mesh surface create a lattice with high contact resistance. It has been seen here and there. The latter is a phenomenon in which, due to the manufacturing and structural characteristics in which the sheet is expanded by making slits, it tends to expand and contract in the expanding direction even with a small external force, and the active material filled in the space inside the mesh tends to fall off.

ことが必要である。EXAMPLE An example of a negative electrode grid used in a high-output lead-acid battery according to the present invention will be described with reference to FIG. Reference numeral 1 denotes a rectangular mesh formed by expanding copper or copper alloy seeds, and 2 represents an unexpanded band-shaped portion, which is integrated with one side 1' of the edge of the rectangular mesh perpendicular to the expanding direction. 3 is a lead or lead alloy bar that is integrated with the grid ears 4. In order for the mesh 1 to expand sufficiently, it is necessary to make cuts in the sheet at sufficient intervals and to make the expanded crosspieces of the mesh slope at an angle of 45° or more. As a result, the copper or copper alloy mesh has hexagonal openings. This hexagonal shape needs to be elongated vertically within the battery, that is, in the expanding direction.
