Lead-acid storage battery curved plate gate structure

Abstract

A lead-acid storage battery curved plate gate structure relates to the technical field of batteries. The lead-acid storage battery curved plate gate structure comprises a frame, vertical ribs, horizontal ribs and a tab. The frame comprises a first horizontal frame, a second horizontal frame, a first vertical frame and a second vertical frame. The plurality of vertical ribs are arranged between thefirst horizontal frame and the second horizontal frame, the plurality of horizontal ribs are arranged between the first vertical frame and the second vertical frame, the tab is arranged on the firstvertical frame, the vertical ribs are arranged on the horizontal ribs in a staggered mode and in a wavy shape, the cross sectional areas of the horizontal ribs are gradually reduced from the first vertical frame to the second vertical frame, the cross sectional area of the first vertical frame is larger than the cross sectional area of the second vertical frame, the closer the horizontal rib getsto the tab, the bigger the cross sectional area of the horizontal rib is, so that it is convenient for current conduction, two of horizontal ribs at the upper and lower portions of the first verticalframe and the second vertical frame are reinforcing horizontal ribs, and the cross sectional areas of the reinforcing horizontal ribs are larger than these of the horizontal ribs. The lead-acid storage battery curved plate gate structure can facilitate production, can effectively reduce the lead usage amount and pole plate resistance, can save cost, can improve the specific energy of the battery,is not easy to deform and fall off, and can prolonging the service life.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a curved panel grid structure of a lead-acid battery. Background technique [0002] Lead-acid batteries are low in price, easy to manufacture, high in capacity and stable, and are widely used in many fields. In the production process of lead-acid batteries, the grid is the most basic production link and the most basic component. The grid is the skeleton of the battery, responsible for supporting and adhering the active material, collecting, converging, transporting, and evenly distributing the current on the plate. As a support for the active material, the grid keeps the active material attached and keeps the plate in a certain shape; the grid acts as a conduction current, so that the current is distributed as evenly as possible in every part of the active material, forming a relatively uniform conductor. [0003] At present, in order to increase the specific energy ...

AI Technical Summary

Problems solved by technology

However, there are problems such as poor corrosion resistance, poor bonding force between the grid and the living matter, and uneven coating.
