Abstract
The invention provides a lead-acid battery grid structure which comprises an outer frame and internal ribs. The internal ribs are thin and dense, and thickness or diameter of the internal ribs is less than or equal to 1/2 of thickness of the outer frame but greater than or equal to 1.2 mm. spacing between each two adjacent internal ribs is 5-15 mm. Thick ribs which have consistent thickness with the outer frame are arranged at the inner part of the outer frame. The lead-acid battery grid structure is used for making a battery plate. During pasting, the pasting thickness is easy to control and consistency is good. Contact area between the ribs and lead paste is large so as to improve current distribution. The distance between the lead paste and the ribs is near. Capacity loss caused by softening of the lead paste is alleviated. Thus, battery performance is enhanced and service life of a battery is prolonged.
Description
Technical field
The present invention relates to lead acid accumulator industry, be specifically related to a kind of novel lead acid accumulator plate grid structure.
Background technology
Along with the development of lead-acid battery grid alloy technology, the battery failure being caused by grid corrosion reduces increasingly, but lead plaster softening be still the one of the main reasons of battery failure.On market, more battery pole plates is lead plaster parcel grid, and the softening of lead plaster certainly will appear in battery at work.Existing lead acid accumulator plate grid inner rip spacing is larger, and inner rip thickness is generally slightly less than outer rim thickness, and after painting cream, electrode thickness is difficult controls, and consistency is bad.This will directly cause battery compression than declining, and between barrier film and pole plate, pressure reduces to aggravate acid solution layering in battery, also can cause that the lead plaster far away apart from rib cannot participate in reaction, cause battery capacity decay.
Summary of the invention
The object of the invention is to overcome the weak point of existing grid, provide a kind of be coated with cream after electrode thickness consistent, improve CURRENT DISTRIBUTION in pole plate, improve battery performance and the lead acid accumulator plate grid structure in useful life.
Technical scheme of the present invention is: a kind of lead acid accumulator plate grid structure, comprise outer rim and inner rip, its improvements are that described inner rip is thin and close, and inner rip thickness or diameter are less than or equal to 1/2 of outer rim thickness, but be more than or equal to 1.2mm, the spacing between inner rip is 5～15mm.
Described outer rim inside is provided with thick rib, thickness and the outer rim consistency of thickness of thick rib.
Beneficial effect of the present invention:
1, this structure grid is more prone to control in the time of smear, and electrode thickness is more even, and monolithic pole plate Tu cream amount is more easily controlled, and pole plate consistency is better; Due to even thickness, after assembling, between pole plate, compression ratio is close, improves battery performance;
2, grid inner rip is thinner, and distribution comparatively dense increases rib and lead plaster contact area, improves CURRENT DISTRIBUTION in pole plate; Lead plaster and inner rip close together, slow down the softening capacitance loss bringing of lead plaster;
3, outer rim inside is provided with thick rib, increases grid intensity;
4, pressed sheet grid outer rim after cast panel, increases metal lattice density, increases frame intensity and corrosion resistance.
Brief description of the drawings
Fig. 1 is grid structure schematic diagram.
Fig. 2 is A-A place profile in Fig. 1.
Embodiment
Referring to Fig. 1, Fig. 2, the inner rip 2 in grid is thin and close, and inner rip is cylindrical, and its diameter is 1/2 of outer rim 1 thickness, and the spacing in this example between inner rip is 10mm, and inner rip diameter is 2mm.The inside of outer rim is provided with the thick rib 3 of vertical and horizontal, thickness and the outer rim consistency of thickness of thick rib.
Claims (2)
1. a lead acid accumulator plate grid structure, comprises outer rim and inner rip, it is characterized in that described inner rip is thin and close, and inner rip thickness or diameter are less than or equal to 1/2 of outer rim thickness, but are more than or equal to 1.2mm, and the spacing between inner rip is 5～15mm.
2. by lead acid accumulator plate grid structure described in claim 1, it is characterized in that described outer rim inside is provided with thick rib, thickness and the outer rim consistency of thickness of thick rib.
