Description
Technical field
The present invention relates to storage battery and be internalized into special grid.
Background technology
Container formation changes into traditional slot type and compares, and has many advantages, and its technological process simplifies pole plate changes into washing, dry and battery supplements electricity and slot type changes into load, gets the operations such as sheet.Save a large amount of man-hour and the energy, need not purchase electrolytic bath equipment and acid-mist equipment, battery cost also can obtain certain reduction, and decrease the turnover operation of pole plate, pole plate is not easily polluted by impurity, can reduce self-discharge of battery, and battery quality also can be controlled better.
But container formation is compared with tank formation, there is the phenomenon that hickie is difficult to eliminate bottom positive plate, the hickie bottom positive plate is in battery charge and discharge process, and the ion of electrolyte is difficult to penetrate hickie and arrives negative pole, therefore the response area of pole plate reduces, and affects the heavy-current discharge performance of battery.Meanwhile, because ion is difficult to penetrate hickie arrive negative pole, the discharge and recharge that substantially do not participate in of the active material at the corresponding hickie position of negative pole is reacted, and in charge and discharge cycles process, this position easily produces the accumulation of bulky grain lead sulfate and produces argillization phenomenon.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of storage battery and is internalized into special grid, fundamentally solves the problem of hickie bottom positive plate.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of storage battery is internalized into special grid, comprise grid body, grid body top is provided with lug, the surface of grid body is provided with rib, described rib forms latticed structure by transverse rod strip and vertical rib strip square crossing, and the active contacts area of transverse rod strip successively reduces to top bottom grid, and the active contacts area of vertical rib strip successively reduces to lug position from grid both sides frame.
Preferably, described transverse rod strip by bottom grid to top from dense to sparse.
Preferably, the cross section of described rib is rhombus, and the cross-sectional area of rib remains unchanged along its length.
Preferably, the ratio that transverse rod strip rhombus is wide with high successively reduces to top bottom grid, and the ratio that vertical rib strip rhombus is wide with high successively reduces to lug position from grid both sides frame.
Preferably, along with transverse rod strip and vertical rib strip diamond-shaped cross-section is wide and a high proportion of change, active material response area is increased to 5.39x4xh by 4.72x4xh, the length of unit to be mm, h be rib.
The present invention is in the prerequisite not changing grid weight, according to the distribution of electric current at grid, the object of optimal design is reached by the contact area adjusting active material and each position of grid, improve the electric conductivity of storage battery, improve accumulator property, be beneficial to optimization grid structure of storage battery, be specially adapted to being internalized into of high type pole plate or thick plate-type battery.

Fig. 2 is A-A cutaway view in Fig. 1;
Fig. 3 is C-C cutaway view in Fig. 1;
Fig. 4 is the schematic diagram of rib cross section when active contacts area is the most little;

Embodiment
As shown in Figure 1, storage battery of the present invention is internalized into special grid, comprises grid body 1, and grid body top is provided with lug 3, and the surface of grid body is provided with rib 2, and described rib forms latticed structure by transverse rod strip 20 and vertical rib strip 21 square crossing.
The present invention is in the prerequisite not changing grid weight, according to the distribution of electric current at grid, the object of optimal design is reached by the contact area adjusting active material and each position of grid, the concrete active contacts area being designed to transverse rod strip 20 successively reduces to top bottom grid, and the active contacts area of vertical rib strip 21 successively reduces to lug 3 position from grid both sides frame.
Wherein, described transverse rod strip by bottom grid to top from dense to sparse.Increase the response area of active material bottom pole plate, optimize the reaction that grid respectively asks position active material, improve formation efficiency.
As shown in Figures 2 and 3, the cross section of described rib is rhombus, and the cross-sectional area of rib remains unchanged along its length.The ratio that transverse rod strip rhombus is wide with high successively reduces to top bottom grid, and the ratio that vertical rib strip rhombus is wide with high successively reduces to lug position from grid both sides frame.
By the ratio changing transverse rod strip rhombus wide, high, the present invention ensures that the contact area to grid top of active material bottom grid is linearly successively decreased (as shown in Figure 2, Fig. 1 cross section view A-A is successively decreased to B point by A point) thus ensure the conversion of active material bottom grid.
By the ratio changing rhombus wide, high, the present invention ensures that active material linearly successively decreases (as shown in Figure 3 by frame to lug position in the contact area with perpendicular rib, Fig. 1 cross section view C-C is successively decreased to D point by C point, successively decreased to F point by E point), thus ensure the conversion of grid away from the active material at lug position.
As shown in Figure 4 and Figure 5, along with transverse rod strip and vertical rib strip diamond-shaped cross-section is wide and a high proportion of change, active material response area is increased to 5.39x4xh by 4.72x4xh, the length of unit to be mm, h be rib.
Transverse rod strip, when sectional area remains unchanged, by changing wide with the high ratio of cross section rhombus, being read to top and successively being reduced response area, making active material more balanced in the reaction of grid, thus optimize the grid design be internalized into bottom grid.Perpendicular rib is when sectional area remains unchanged, and by changing wide with the high ratio of cross section rhombus, from grid both sides, frame successively reduces response area to lug position, makes active material balanced in the reaction of grid, optimizes grid structure design.
