Description
Technical field
The utility model discloses a kind of soft bag lithium ionic cell lug sheet, belong to technical field of lithium ion.
Background technology
Soft bag lithium ionic cell energy density is big, and high rate performance and security performance are good, are increasingly used widely.Development along with lithium ion battery applications, people are not only more and more higher to the performance requirement of lithium ion battery, and the consistency of performance of lithium ion battery is had higher requirement, especially require the soft bag lithium ionic cell that each producer efficient conformity of production of high automation equipment is good.Soft bag lithium ionic cell tab welding operation is soft bag lithium ionic cell important procedure, lug downhand welding automaticity is high, production efficiency concordance is good, but in order to improve welding stability and ensure that battery pole ear foil is without damage, a lug metal can be welded with material sheet metal at the another side of foil soldering polar ear sheet during welding simultaneously, to ensure that lug sheet opposite side battery foil is not damaged by, ensure supersonic welder upper and lower soldering tip welding concordance simultaneously, improve welding stability, so connect soft bag lithium ionic cell foil side at lug sheet and add sheet metal complex procedures, lack of homogeneity when soft bag lithium ionic cell electric current is derived by metal tabs, have impact on the large current discharging capability of soft bag lithium ionic cell and the concordance of soft bag lithium ionic cell.This is accomplished by finding a kind of soft bag lithium ionic cell lug, need not during welding position at the opposite side of foil add sheet metal, and it is good to enable to soft bag lithium ionic cell electric current uniformity when lug is derived, improve charging and discharging capabilities and the concordance of soft bag lithium ionic cell of soft bag lithium ionic cell.
Summary of the invention
For the problems referred to above, this utility model provides a kind of soft bag lithium ionic cell lug sheet, to improve processing characteristics and the charge-discharge performance of soft bag lithium ionic cell.
To achieve these goals, this utility model adopts the following technical scheme that realization:
A kind of soft bag lithium ionic cell lug sheet, it is characterized in that: in the middle of a rectangle sheet metal, be provided with bending trace, sheet metal doubling, PP blob of viscose it is provided with at sheet metal two ends, described PP blob of viscose is rectangle, and PP blob of viscose is positioned at sheet metal folding line and the ratio of sheet metal end is 3:7 and the position near end；2 ~ 3 times of a length of sheet metal width of described PP blob of viscose；Described sheet metal is that aluminum, nickel, copper nickel plating one therein are made.
A kind of soft bag lithium ionic cell lug sheet, this soft bag lithium ionic cell lug sheet is made up of sheet metal and PP blob of viscose.Sheet metal symmetrical fold, PP blob of viscose alignment overlap, sheet metal can be the materials such as aluminum, nickel, copper nickel plating, depending on size is according to concrete soft bag lithium ionic cell.During welding, sheet metal (1) symmetrical fold is alignd, sheet metal head portion is individually positioned in the upper and lower surface of soft bag lithium ionic cell foil and carries out tab welding, during welding, lug both sides sheet metal is welded by the upper and lower soldering tip of ultrasonic bonder simultaneously, can effectively reduce the rosin joint produced due to upper and lower soldering tip contact material difference in welding process or cross weldering, welding concordance is good, soft bag lithium ionic cell foil does not comes off, welding effect is good, and both sides lug sheet encases soft bag lithium ionic cell foil, soft bag lithium ionic cell electric current is by homogeneous current distribution during battery pole ear, heat production is few, it is effectively increased the charge-discharge performance of battery.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein: 1, sheet metal, 2, PP blob of viscose.
Detailed description of the invention
Below by embodiment and combine accompanying drawing the technical solution of the utility model is further described.
As it is shown in figure 1, a kind of soft bag lithium ionic cell lug sheet, this soft bag lithium ionic cell lug sheet is made up of sheet metal (1) and PP blob of viscose (2).Sheet metal (1) symmetrical fold, PP blob of viscose (2) alignment overlap, sheet metal can be the materials such as aluminum, nickel, copper nickel plating, depending on size is according to concrete soft bag lithium ionic cell.During welding, sheet metal (1) symmetrical fold is alignd, sheet metal head portion is individually positioned in the upper and lower surface of soft bag lithium ionic cell foil and carries out tab welding, during welding, lug both sides sheet metal is welded by the upper and lower soldering tip of ultrasonic bonder simultaneously, can effectively reduce the rosin joint produced due to upper and lower soldering tip contact material difference in welding process or cross weldering, welding concordance is good, soft bag lithium ionic cell foil does not comes off, welding effect is good, and both sides lug sheet encases soft bag lithium ionic cell foil, soft bag lithium ionic cell electric current is by homogeneous current distribution during battery pole ear, heat production is few, it is effectively increased the charge-discharge performance of battery.
A kind of soft bag lithium ionic cell lug sheet, it is characterized in that: in the middle of a rectangle sheet metal 1, be provided with bending trace, sheet metal 1 doubling, overlap after sheet metal 1 doubling, sheet metal 1 is provided with PP blob of viscose 2 at two ends, described PP blob of viscose 2 is rectangle, and described sheet metal 1 is aluminum, nickel, copper nickel plating one therein are made.
PP blob of viscose 2 is positioned at sheet metal 1 folding line and the ratio of sheet metal 1 end is 3:7 and the position near end；2 ~ 3 times of a length of sheet metal 1 width of described PP blob of viscose 2；PP blob of viscose width ratio metal two ends width the widest go out 5 ~ 10mm.
