Abstract
The utility model discloses a plumbous calcium grid structure of corrosion resistant lead acid battery, include the body, connect the utmost point ear in body one side, the body includes bars frame and the rib that is located bars frame zigzag connection, the rib cross -section is the rhombus, poor <= 0.3mm of rib thickness an and rib width b, and rib thickness an is greater than rib width b. Furthermore, rib thickness an is 0.8~1.2mm. Furthermore, rib width b is 1~1.4mm. The utility model discloses under the condition of costneutrality, prolonged the corrosion -resistant time of grid, prolonged lead acid battery's life.
Description
Technical field
The utility model belongs to lead-acid accumulator field, more particularly to a kind of corrosion resistant Lead-acid Storage Battery calcium grid
Structure.
Background technology
The construction of lead-acid accumulator mainly includes cell body, pole plate, dividing plate, electrolyte, pole etc..Wherein pole plate is battery
Core component.Pole plate is constituted by the lead plaster as active material and as the grid of support frame and electric action, and lead
The discharge and recharge of acid accumulator is completed mainly by grid, so the shape of grid, appearance and size and structure are all to affect cell performance
The key factor of energy.
The lead acid accumulator plate grid majority for now producing is lead calcium series alloy, is obtained using gravity casting processing, and calcium is just
Play a part of to increase grid intensity in the alloy of pole, and calcium has lower overpotential than lead, therefore be easier to cause electrochemistry rotten than lead
Erosion.The difference of the diamond-shaped cross-section diagonal distance of existing grid rib is larger, and the corrosion of grid is inside from section of ribs outside
Portion corrodes, certain in corrosion rate, and cross-sectional area is certain, in the case that grid weight is certain, diamond-shaped cross-section diagonal distance
Difference it is bigger, the etching time that can be born is shorter, and grid corrosion causes afterwards to a certain extent rib to rupture, then battery loses rapidly
Effect.
Utility model content
The purpose of this utility model is：To overcome the deficiencies in the prior art, there is provided a kind of not increase material consumption
In the case of, strengthen grid corrosion resistance, extend the grid structure of grid corrosion-resistant time.
For achieving the above object, the technical solution of the utility model is：
A kind of corrosion resistant Lead-acid Storage Battery calcium grid structure, including body, the lug of body side is connected to, it is described
Body includes grid frame and the rib being cross-linked positioned at grid inframe, and the section of ribs is rhombus, rib thickness a and rib width
Difference≤the 0.3mm of b, and rib thickness a is more than rib width b.
Further, the rib thickness a is 0.8~1.2mm.
Further, the rib width b is 1~1.4mm.
As a result of such scheme, the beneficial effects of the utility model are：Prior art problem is solved, due to plate
Gate etching is, externally to inside, from tip or thin position corrosion to be started, so the utility model rib thickness a and rib width
Difference≤the 0.3mm of degree b, and rib thickness a is more than rib width b so that under conditions of cost is not increased, reduce rhombus
Diagonal cross section is apart from its difference so that the time that grid bears corrosion is longer, so as to extend the corrosion-resistant time of lead-acid accumulator.
Description of the drawings
Fig. 1 is the structural representation of grid.
Fig. 2 is the sectional view of rhombus rib in prior art.
Fig. 3 is the sectional view of rhombus rib in the utility model.
Reference：1- bodies, 2- lugs, 3- grid frames, 4- ribs.
Specific embodiment
Embodiment：With reference to Fig. 1, Fig. 2, Fig. 3, a kind of corrosion resistant Lead-acid Storage Battery calcium grid structure, including body 1,
The lug 2 of the side of body 1 is connected to, the body 1 includes grid frame 3 and the rib 4 being cross-linked in grid frame 3, the muscle
The section of bar 4 is rhombus, and the above-below direction in section is the thickness direction of rib, and the left and right directions in section is the width of grid,
Rib thickness is less in prior art, and rib width is larger, and both differences are larger, and grid two sides are perishable, and rib ruptures,
So that the service life of lead-acid accumulator is short, and the difference≤0.3mm of rib thickness a of the present utility model and rib width b, and muscle
Bar thickness a is more than rib width b, increases diagonal distance, extends the grid corrosion-resistant time, extends lead-acid accumulator
Service life.
The a of rib thickness described in the present embodiment is 0.8~1.2mm.
The b of rib width described in the present embodiment is 1~1.4mm.
