加工したメツシユが用いられることが多い。Conventional technology and its problems Lead alloys are generally used for the grids of lead-acid batteries, and their electrical resistance is 21 x 10 -6 Ωcm, which is one of the highest 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. By the way, the electrical resistance of copper is 1.7×10 -6 Ω・cm, 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 often used.

していた。 When grids are made of copper material, there are problems with electrical and mechanical bonding to the strips or poles. In the example that has been put into practical use so far, one side of the mesh made of copper material is cast, that is, molten metal is poured into the mold and cooled and solidified, and the grid ears and current collector strips made of lead material are made of copper material. were integrated.

あつた。 As is well known, copper materials are easily oxidized in humid air, and a dense oxide film is formed particularly at high temperatures. For casting lead or lead alloys, temperatures of 150~
Molten metal is poured into a mold at 200°C, but in such a high temperature atmosphere, even copper with a normal surface will oxidize, so if it is connected to a lead bar by casting, the copper mesh will be covered with an oxide film. The melting temperature of copper oxide is 1235°C, and it does not melt at the temperature of molten lead of 400°C to 500°C. Therefore, there was a problem in that the electrical and mechanical connection between the copper mesh and the lead current collection strip was incomplete, resulting in a large voltage drop during high-output discharge.

By joining the green portion and the two strips together, the problems of conventional copper or copper alloy grids are solved.

Reference numeral 1 is a rectangular mesh formed by expanding copper or an alloy sheet mainly composed of copper, 2 is a strip made of lead or an alloy mainly composed of lead, and 3 is a lattice lugs which are integrated with the strip 2. Reference numeral 1' denotes a green portion on one side of the mesh 1, which is electrically and mechanically connected to the strip 2 made of lead material. The surface of the mesh 1 made of copper material is preferably coated with lead or a lead-based alloy by plating, metallic coating, dipping, etc., before or after joining the mesh 1 to the strip 2. This is because the hydrogen overvoltage of copper material is smaller than that of lead material, which eliminates the disadvantage of increasing self-discharge of the negative electrode plate.

Do this by doing this. The oxide film on the surface of the green part 1' is destroyed by the ultrasonic vibration and mixed into the molten lead material, and the normal copper material is exposed on the surface, and in the solidified state, the green part 1' and the strip 2 are mixed. is electrical,
