Technical problem to be solved in the utility model, exactly for storage battery discharging and recharging in use procedure, active material in pole plate can fill out in pole plate, in addition the tension that dividing plate contacts with positive/negative plate, active material after shedding does not have decline passway to decline, will be deposited in the middle of positive/negative plate, when overheap, positive/negative plate has been linked to be to path, cause the problem of internal storage battery short circuit or micro-short circuit, pouch type secondary battery dividing plate is provided, after reaching the shedding of minimizing active substance of battery, be deposited in the possibility that causes internal storage battery short circuit or micro-short circuit between positive/negative plate.
The utility model solve the technical problem, the technical scheme adopting is, pouch type secondary battery dividing plate, comprise dividing plate housing and dividing plate muscle that upper side frame, lower frame, left frame and left frame connect into, the two ends of dividing plate muscle are arranged at respectively on upper side frame and lower frame, and have certain distance with left frame and left frame, the thickness of dividing plate muscle starts to lower frame progressive additive from upper side frame.
Concrete, the quantity of described dividing plate muscle is no less than one, between dividing plate muscle on the left side frame and left frame for being uniformly distributed.
Concrete, between dividing plate muscle on the left side frame and left frame, be that equally distributed spacing range is 10mm～20mm.
Further, the thickness range of described upper side frame, lower frame, left frame and left frame is 0.5mm～1.1mm, and the initial thickness scope of dividing plate muscle is upper side frame thickness～2mm, and the termination thickness range of dividing plate muscle is dividing plate muscle initial thickness～3mm.
Further, described dividing plate upper side frame width range is 10mm～30mm, and lower frame width range is 2mm～10mm, and left frame and left frame are wide, and width range is 7mm～15mm, and the width range of dividing plate muscle is 2mm～7mm.
Further, the quantity of described dividing plate muscle is mated by the size of spacer width.
Further, described dividing plate muscle is polyolefin separator muscle.
Further, described dividing plate muscle is poly-halogen alkene dividing plate muscle.
The beneficial effects of the utility model are, thickness by reasonable Arrangement dividing plate muscle and position, when taking into account membrane support power, reduced the thickness of dividing plate other parts, when dividing plate and positive/negative plate clamping, only have dividing plate foot muscle and positive/negative plate to clamp, the other parts of dividing plate and positive/negative plate become with regard to slot milling the passage that active substance of battery declines, after greatly having reduced active substance of battery shedding, be deposited in the possibility that causes internal storage battery short circuit or micro-short circuit between positive/negative plate, reduced the generation of quality accident; Because the segment thickness of dividing plate except muscle declines, the integral material consumption of dividing plate has also declined, and then has reduced the cost of storage battery, has improved product competitiveness.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model pouch type secondary battery dividing plate;
Wherein, 1--upper side frame, 2--lower frame, 3--left frame, 4--left frame, 5--dividing plate muscle, 6-dividing plate.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail:
The utility model for storage battery discharging and recharging in use procedure, active material in pole plate can fill out in pole plate, in addition the tension that dividing plate contacts with positive/negative plate, active material after shedding does not have decline passway to decline, will be deposited in the middle of positive/negative plate, when overheap, positive/negative plate has been linked to be to path, cause the problem of internal storage battery short circuit or micro-short circuit, pouch type secondary battery dividing plate, as shown in Figure 1, comprise upper side frame 1, lower frame 2, left frame 3, left frame 4 and dividing plate muscle 5, upper side frame 1, lower frame 2, left frame 3 and left frame 4 connect into rectangular clapboard 6 housings, the two ends of dividing plate muscle 5 are arranged at respectively on upper side frame 1 and lower frame 2, and there is certain distance with left frame 3 and left frame 4, the thickness of dividing plate muscle 5 starts to lower frame 2 progressive additives from upper side frame 1.Thickness by reasonable Arrangement dividing plate muscle and position, when taking into account membrane support power, reduced the thickness of dividing plate other parts, when dividing plate and positive/negative plate clamping, only have dividing plate foot muscle and positive/negative plate to clamp, the other parts of dividing plate and positive/negative plate become with regard to slot milling the passage that active substance of battery declines, and are deposited in the possibility that causes internal storage battery short circuit or micro-short circuit between positive/negative plate after greatly having reduced active substance of battery shedding.
