Part of the body with the mass flow. The utility model discloses a mass flow of the cylinder body, the conversion zone of contact battery that can be even, the even produced electronics of absorption reaction of capacity, the increase mass flow is personally experienced sth. Part of the body and anodal area of contact, has reduced electron transfer's distance, has improved the uniformity of battery, and battery capacity is big current discharge capacity especially.
Description
Technical field
The utility model relates to the sub-battery current collecting body structure of a kind of lithium.
Background technology
The collector of current lithium thionyl chloride cell is general as shown in Figure 1, center pole 53 is welded with nickel and draws in the net, this design mainly increases catchment area, reduce the internal resistance of battery, but this structure fundamentally can not effectively reduce the internal resistance of battery, improve the capacity especially heavy-current discharge electric current of battery, and this structure is comparatively large to positive pole wound when cell assembling processes collector 52 inserts positive pole 51, bad to battery with two side terminals.
Utility model content
In order to solve the problems referred to above that prior art exists, the purpose of this utility model proposes the sub-battery current collecting body structure of a kind of lithium, effectively to solve battery consistency, battery capacity, and heavy-current discharge problem.
For achieving the above object, the utility model is solved by following technical scheme:
The sub-battery current collecting body structure of a kind of lithium, comprise positive polar body, center pole, collector, this collector coupling is glued and placed in the centre bore of cylindric positive polar body, this collector is cylindrical shape, on cylindrical wall, uniform Design has through hole, the inside flanging in bottom of this cylinder, the outside flanging in top, this top outside flanging coupling is affixed on described positive polar body top surface, and a metallic contact strips connects described center pole and collector.
As preferred technical scheme:
The sub-battery current collecting body structure of lithium described in the utility model, the inside flanging in described bottom is 2 ~ 2.2mm; The outside flanging in top is 3 ~ 3.2mm, and collector wall thickness of cylinder is 0.2 ~ 0.25mm.
Li Ya battery collective described in the utility model body structure, described metallic contact strips cross section is circular, and diameter is 0.1 ~ 0.5mm.
The sub-battery current collecting body structure of lithium described in the utility model, described through hole is circular, and diameter is 2 ~ 3mm.
Owing to adopting above technical scheme, the utility model is by columnar nickel collector, the conversion zone of battery can be contacted uniformly, can the electronics that produces of the absorption reaction of even capacity, increase the contact area of collector and positive pole, reduce the distance of electron transmission, improve battery with two side terminals, battery capacity is heavy-current discharge capacity particularly, and can adjust the size of cylindrical shape collector according to the battery of different model, to meet the demand in market.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing collector;
Fig. 2 is the structural representation of collector in the utility model;
Fig. 3 is that the utility model collector is positioned over the structural representation after in positive polar body.
