Abstract
The utility model provides a double-tab positive plate, which comprises a plate body. Two tabs are arranged on the upper border of the plate body, and are the distance of 5 to 10mm away from each other. The double-tag positive plate can improve the consistency of active substance utilization rate of the upper and lower parts of the plate, and improve the charging receptivity and high current discharge capability of a storage battery.
Description
Technical field
The utility model relates to storage battery and makes the field, is specifically related to a kind of bipolar ear positive plate.
Background technology
Electric boosted automobile-used lead-acid battery positive plate active material is a brown lead oxide, conductive capability is poor, rely on plate ear position to import the shunting of pole plate frame during charging, equally also mainly rely on limit pole plate frame collected current during discharge, present pole plate all adopts the monopole ear design, monopole ear connects into bus-bar, there is following problem in this structure: the one, and conduction circle sectional area is little, under the heavy-current discharge attitude, its electric current is collected into the narrow and small lug position of lug and pole plate, produces heating, thereby make and improve near the lug position active material coefficient of expansion, the corrosion combination interface of active material and grid is damaged, and causes the active material inefficacy that comes off, shorter battery life; The 2nd, there is the inconsistent situation of assembling pressure up and down at present electric boosted automobile-used lead acid accumulator, end opening on average is higher than 20KPa suitable for reading, so the top electrolyte content is greater than the bottom, in charging process, extreme difference is inconsistent up and down, CURRENT DISTRIBUTION density top is higher than the bottom, the transfer ratio that the α brown lead oxide is converted into beta lead dioxide in the active material of pole plate top is higher than the bottom active material, cause the top active material utilization to be higher than the bottom thus, repeatedly after the circulation, the top active material is softening to quicken, and the life of storage battery finishes in advance.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bipolar ear positive plate, can improve the consistency of the active material utilization of pole plate top and bottom, improves the charge acceptance and the large current discharging capability of storage battery.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of bipolar ear positive plate, comprise the pole plate main body, and the upper side frame of described pole plate main body is provided with two lugs, and the distance between described two lugs is 5～10mm.
As preferably, be provided with 3～4 between the left and right side frame muscle of described two lugs and pole plate main body and the lower frame and present radial diagonal bar.During charging, electric current uniformly is distributed to polar board surface by diagonal bar and frame muscle with electric current from two lug positions, and during discharge, electric current is flowed to two lug positions from frame muscle position and diagonal bar, improve the uniformity of CURRENT DISTRIBUTION density, thereby improved active material utilization.
Beneficial effect:
The utility model adopts technique scheme that a kind of bipolar ear positive plate is provided, and can improve the consistency of the active material utilization of pole plate top and bottom, improves the charge acceptance and the large current discharging capability of storage battery.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of bipolar ear positive plate comprises pole plate main body 1, and the upper side frame of described pole plate main body 1 is provided with two lugs 2, and the distance between described two lugs 2 is 5～10mm.Behind the battery coating, realize anodal double bus welding, increased the contact area of lug and pole plate, reduce the resistance at this position of charge or discharge attitude, especially can allow the heavy-current discharge of short time and quick charge the time pole plate heating more even, reduce the potential difference of pole plate different parts, make polarization speed reach unanimity.Be provided with 3～4 between the left and right side frame muscle of described two lugs 2 and pole plate main body 1 and the lower frame and present radial diagonal bar 3.During charging, electric current uniformly is distributed to polar board surface by diagonal bar and frame muscle with electric current from two lug positions, and during discharge, electric current is flowed to the lug position from frame muscle position and diagonal bar, improve the uniformity of CURRENT DISTRIBUTION density, thereby improved active material utilization.
