Title: Electrode base plates for lead storage battery
Inventor: NAGATA YUKIHIRO
IPC: H01M4/73
Filed: 1984-02-09
Abstract: PURPOSE:To prevent any curving of electrode plates which might occur due to their expansion by specifying the ratio of the length of vertical grid bones to that of lateral grid bones which form each space into which an active material is to be packed when grid-like base plates are prepared from a thin lead-alloy plate by punching. CONSTITUTION:When forming electrode base plates 1 for a lead storage battery, the ratio of the length (a) of vertical grid bones 4 to the length (b) of lateral grid bones 5 is adjusted to be more than 1 preferably about 3.5; two vertical grid bones 4 and two lateral grid bones 5 surround each space 6 into which an active material is to be packed. As a result, after a plate group is made by fixing the lug 2 and the legs 3 of each base plate 1 to a strap and a container, the vertical expansion of the base plate 1 is smaller than its lateral expansion. Therefore the is no possibility that the plate formed by packing the active material is deformed due to curving or similar cause. Accordingly the reliability and the life of the plates can be improved by preventing any separation of the active material from the plates or short circuits between the plates.
