Abstract
The utility model provides a flexible package lithium battery. The flexible package lithium battery comprises multiple sections of electric cores, each electric core is provided with two tabs, and the two tabs are respectively an anode tab and a cathode tab; the flexible package lithium battery further comprises a welded plate, a tab bonding pad is arranged on the welded plate, a strip-shaped groove is formed on the tab bonding pad, and the length of the strip-shaped groove is matched with the widths of the anode tabs and the cathode tabs. According to the flexible package lithium battery provided by the utility model, the anode tabs and the cathode tabs of the electric cores are welded on the tab bonding pad of the welded plate, the welding process is simple and not prone to generating welding errors, the welded plane is flat, a voltage detection end of each electric core can be directly led out by a pin, and a process of leading wires again on the welding spots of the tabs is not needed.
Description
Technical field
The utility model relates to soft package lithium battery, specifically, relates in particular to a kind of soft package lithium battery with welded plate.
Background technology
Usually by more piece battery core combination serial connection, as shown in Figure 1, every economize on electricity core is provided with positive pole ear and negative lug to soft package lithium battery, and when the more piece battery core was connected in series, positive pole ear, the negative lug of adjacent two battery cores were connected successively.The positive pole ear of existing soft package lithium battery, negative lug adopt and directly are welded to connect, yet because the lug of battery core is the rectangle copper sheet, weld more consuming time, the welding mistake appears easily, battery core is more, and pad is more, and the easier appearance of solder side is rough and uneven in surface, when detecting each battery core voltage, need to again draw the collection line in connection welding.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of soft package lithium battery is provided, and welding is simple, is not easy to occur the welding mistake, and solder side is smooth, and the voltage detecting end of each battery core can directly draw by contact pin, need to be on the lug solder joint lead-in wire again.
For achieving the above object, the utility model has adopted following technical proposal: a kind of soft package lithium battery is provided, comprise the more piece battery core, every economize on electricity core is equipped with two lugs, and described two lugs are respectively positive pole ear and negative lug, wherein, also comprise welded plate, described welded plate is provided with the lug pad, has bar-shaped trough on this lug pad, and the length of described bar-shaped trough matches with the width of positive pole ear, negative lug.
Above-mentioned soft package lithium battery, wherein, described lug pad is rectangle.
Above-mentioned soft package lithium battery wherein, also is provided with the contact pin pad on the described welded plate, and this contact pin pad is by conducting medium connecting tab pad.
Above-mentioned soft package lithium battery, wherein, described contact pin pad is circular.
Above-mentioned soft package lithium battery wherein, is fixedly connected with contact pin in the described contact pin pad.
Above-mentioned soft package lithium battery, wherein, described conducting medium is Copper Foil.
Compared with prior art, the utility model has the advantage of: the soft package lithium battery that the utility model provides, positive pole ear, the negative lug of battery core are welded at the lug pad of welded plate, welding is simple, be not easy to occur the welding mistake, solder side is smooth, and the voltage detecting end of each battery core can directly draw by contact pin, need to be on the lug solder joint lead-in wire again.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of battery core;
Fig. 2 is the structural representation of the utility model one soft package lithium battery;
Fig. 3 is the structural representation of welded plate among Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 2, the soft package lithium battery that the utility model provides, comprise more piece battery core 1, every economize on electricity core 1 is equipped with two lugs 2, described two lugs 2 are respectively positive pole ear and negative lug, wherein, also comprise welded plate 4, as shown in Figure 3, described welded plate 4 is provided with the lug pad 41 of rectangle, have bar-shaped trough 42 on this lug pad 41, the length of described bar-shaped trough 42 and positive pole ear, the width of negative lug matches, and the lug 2 of battery core 1 passes from bar-shaped trough 42, and be welded on the corresponding lug pad 41, welding is simple, is not easy to occur the welding mistake, and solder side is smooth.In addition, also be provided with circular contact pin pad 43 on the described welded plate 4, and this contact pin pad 43 is by the conducting mediums such as Copper Foil 44 connecting tab pads 41, be fixedly connected with contact pin 3(in the described contact pin pad 43 such as Fig. 2 shows), and the voltage detecting end of each battery core 1 can directly be drawn by contact pin 3, need to again not go between on the lug solder joint.
In sum, the soft package lithium battery that the utility model provides, positive pole ear, the negative lug of battery core 1 are welded at the lug pad 41 of welded plate 4, welding is simple, be not easy to occur the welding mistake, solder side is smooth, and the voltage detecting end of each battery core 1 can directly draw by contact pin 3, need to be on the lug solder joint lead-in wire again.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
