くなっている。BACKGROUND OF THE INVENTION In recent years, so-called maintenance-free batteries that require low water replenishment frequency and can withstand long-term storage are increasingly using Pb-Ca alloys, which have a large hydrogen overvoltage, as the lattice alloy of the negative electrode plate.
従来の負極板の格子合金としてＰｂ−８ｂ系合金を用い

性に優れ、機械的強度の大きいｐｂ−ｓｂ系合金を用い
ている。In conventional batteries that use Pb-8b alloy as the lattice alloy of the negative electrode plate, it has excellent weldability and is used as a lead material (additional lead and lead parts such as terminals) when welding the electrode plate ears to form the strap. , a pb-sb alloy with high mechanical strength is used.

点があった。Problems to be Solved by the Invention However, in batteries that use a Pb-Ca alloy as the lattice alloy of the negative suspension plate, as a lead material when forming the strap,
When a pb-sb alloy is used, there is a drawback that sb diffuses to the surface of the strap during use or is deposited on the cathode after being dissolved in the electrolyte, reducing the hydrogen overvoltage of the cathode.

のである。Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks by immersing the negative electrode strap portion in silica sol or applying silica sol to the negative electrode strap portion and then drying to form a film.

どを効果的に被覆し、ｓｂの溶出及びｓｂ上のＨ＋→Ｈ
１↑を妨げるものである。By evaporating water from the silica sol, the colloidal particles firmly adhere to the recesses of the strap part, and the particles also form siloxane bonds with each other to form strong bonds, so that solute metal (Sb) and impurities are removed. It effectively covers the defective areas where sb is segregated, and prevents the elution of sb and the H+→H on sb.

A product A of the present invention in which a silica sol according to the present invention was applied and then subjected to a hot air drying treatment. The conventional processed product B was subjected to the following tests.

か判る。Battery: N540ZA (grid is Pb-0a alloy for both anode and cathode) The amount of liquid loss in the SAE life test corresponds to the amount of water electrolysis during the test, and is a parameter that indicates so-called maintenance-free characteristics. , Inventive product A and conventional product B
The difference becomes more noticeable as the cycle progresses.

難い等工業的価値甚だ大なるものである。Effects of the Invention As described above, according to the present invention, a PB-SB alloy with good workability can be used without impairing maintenance-free characteristics, and other coating materials ( For example, since silica sol has a lower viscosity than that of plastics, it can easily penetrate into finer details and is therefore difficult to peel off, making it of great industrial value.
