Abstract

The invention discloses a lead-acid storage battery grid with a confluence lug and a super-pore cut and stretched net being welded together. The grid has the technical characteristics that lead and a lead alloy are rolled into a lead belt according to a required thickness; a super-pore lead net is made with a precision net cutting and stretching process; and the confluence lug made of the lead and the lead alloy is welded integrally with the super-pore lead net through a patch welding process in order to obtain the lead-acid storage battery grid. Through adoption of the grid, the pore size of a lead-acid storage battery grid in the prior art is reduced greatly. Meanwhile, the sizes of grid ribs are reduced, the surface area of the grid is increased greatly, and the active substance utilization ratio of a battery is increased greatly, so that the specific energy, charging / discharging performance and service life of a lead-acid storage battery are improved greatly.

Description

technical field [0001] The present invention relates to the improvement and enhancement of lead-acid storage battery grid. Background technique [0002] At present, the grids of lead-acid batteries in the prior art are basically produced by the gravity casting method, the lead strip continuous rolling expansion method and the lead strip punching method. The hole size of the lead-acid storage battery grid that adopts these methods to produce is big, is generally 6mm * 8mm; The area is small; at the same time, the thickness of the grid of the lead-acid battery in the prior art is large, generally above 1.1 mm. The lead-acid battery plate produced by the prior art grid has low utilization rate of active material, poor charging and discharging performance, low specific energy and short service life of the battery, which cannot meet the needs of the development of lead-acid battery. Contents of the invention [0003] The purpose of the present invention is to produce lead-aci...
