Abstract: A method for preparing a grid alloy of a lead battery, comprising the following steps: (1) preparing an aluminum-lanthanum-cerium rare earth mother alloy by using a molten salt electrolysis method; (2) melting the aluminum-lanthanum-cerium rare earth mother alloy with sodium and partial lead and uniformly stirring same to prepare an intermediate alloy; and (3) melting the intermediate alloy with calcium, tin and remaining lead and uniformly stirring same to form a grid alloy of a lead battery.

Abstract: The invention discloses a horizontal lead storage battery include a battery container and a cover; the interior of said battery container is installed with a partition that divides its inner cavity into a plurality of single cells, and each cell is installed with a plate group; the adjacent plate groups are connected by a bridge; said partition has a gap for the bridge to pass through, and a sealing component is installed at the gap; said sealing component comprises two sealing plates with a gap and sealed with said partition; said gap is filled with sealant. The gap of the partition of present invention is provided with two sealing plates, the gap between the two sealing plates is filled with sealant, and the tiny gap between the sealing plate and the partition is sealed by sealing, thereby improving the sealing effect.
