Abstract
The utility model discloses a profiled battery. The profile battery of the utility model consists of a packaging film, a positive plate, a negative plate, an insulation diaphragm, electrode ears and an electrolyte. The battery can be in regular or irregular geometric shape. A positive ear and a negative ear of the battery are arranged on a same side or different side of the battery. The utility model can be applicable to very narrow battery groups, further makes up for the space and short-circuit problems of the batteries due to the lack of the width of batteries at the same side, effectively prevents the assembly and short-circuit problems in the manufacturing process of battery, and is convenient for connection in series or in parallel. And the setting of a plurality of electrode ears can effectively solve the charge or discharge problem of the high current of batteries. Moreover, because of the different shapes and design of the battery, and the arbitrary adjustment of the direction of the electrode ears, so that the utility model can be greatly adapted to the market demand.
Description
Technical field
The utility model relates to and has difform battery, particularly has the battery of multiple lug position.
Background technology
At present, along with continuous application and the popularization of battery in various electrical equipment, also more and more to the personalization requirement of battery design, the exploitation of comparatively single size can not have been satisfied the demand in market fully.Therefore, make battery make " flexibility " and change, assembling is oversimplified, and shape dress variation etc. becomes the key factor that obtains client's approval and dominate the market.Battery of the prior art, its lug operated by rotary motion make the assembling of battery and design be restricted to a great extent in the same side of battery; Because battery is narrow more, the distance of lug is near more, easy more short circuit simultaneously; When the cell widths direction is too narrow to about 8mm, especially the making of the electric core of coiling and molding hardly may, very easily short circuit, even can't assemble; In addition, the battery in the background technology only has positive and negative two lugs, because the lug of battery is few more, the current density in the unit is big, so the battery in the background technology is not suitable for the high current charge-discharge standard; At last, because the heteromorphosis of battery utmost point group is at first depended in the design of the abnormity of battery structure, therefore the design of the heteromorphosis of battery utmost point group has also become the key of personalized battery design, the shape of the battery in the background technology is stiff, and its shaped design can not adapt to the needs of Battery Market individualized development at all.
The utility model content
The purpose of this utility model has been to overcome the deficiency in the background technology, the special-shaped battery that provides a kind of special-shaped battery utmost point group to be made into.
The technical scheme that the utility model adopted is: special-shaped battery is made of packaging film, positive plate, negative plate, insulation diaphragm, lug and electrolyte.The shape of described battery can be rule or irregular geometry; The anode ear of battery and negative electrode lug can be arranged at the same side of battery or ipsilateral not respectively.
Described lug can be positioned at the homonymy of battery, also can be positioned at the heteropleural of battery.Described battery can be provided with two or more anode ear, two or more negative electrode lug.The quantity of anode ear and negative electrode lug can be identical also can be inequality.
The shape shape of described battery can be rectangle, circle, banana-shaped, polygon, triangle, also can be shape arbitrarily.
The utility model goes for narrower battery, and then has remedied such battery because space problem and the short circuit problem that homonymy cell widths deficiency causes effectively prevented the assembling short circuit problem in the battery manufacture process, and conveniently carried out serial/parallel connection; Simultaneously a plurality of lugs is provided with the big electric current charge/discharge problem that can effectively solve battery; Because design of the difformity of battery and lug are provided with the property adjusted arbitrarily of direction, make the utility model can be adapted to the market demand greatly simultaneously.

Embodiment
Below in conjunction with accompanying drawing part embodiment of the present utility model is elaborated.
Embodiment 1:
As shown in Figure 1, in the present embodiment, battery utmost point group be shaped as rectangle, on a relative side, be respectively arranged with totally two lugs.Battery utmost point group 1 wherein, it can be stacked, also can be coiled, is shaped as rectangle.Lug 2 is the compound terminal to be drawn by the stack of many groups lug also, lug can be welded on the surface of utmost point group ending place utmost point group outside collector, also can be the surface that is welded on utmost point group internal start place collector, promptly can change the derivation direction of lug by the direction that changes them.Lug glue 3 on the lug, its dimension width and thickness can be adjusted according to the variation of lug matrix, are mainly used in the battery packaging film encapsulation, to guarantee excellent sealing performance; The solder joint 4 of welding can be the single-point welding, also can be the multiple spot welding, and suitable adjustment can be done according to the difference of coiling, lamination mode in its position.
After utmost point group had designed, with encapsulating behind the packaging film, the battery that forms after the fluid injection as shown in Figure 2.The anode ear 4 of battery wherein, the negative electrode lug 5 of battery, packaging film 6.
Embodiment 2
As shown in Figure 3, present embodiment is a kind of battery utmost point group with multi-direction lug, and it is shaped as rectangle, is provided with totally four lugs on each side of battery utmost point group respectively in opposite directions.Battery utmost point group 7, it can be stacked, also can be coiled, is shaped as rectangle.Lug 8, also compound terminal to draw by the stack of many groups lug, lug can be welded on the surface of utmost point group ending place utmost point group outside collector, also can be the surface that is welded on utmost point group internal start place collector, promptly can change the derivation direction of lug by the direction that changes them.Lug glue 9 on the lug, its dimension width and thickness can be adjusted according to the variation of lug matrix, are mainly used in the battery packaging film encapsulation, to guarantee excellent sealing performance; The solder joint 10 of welding can be the single-point welding, also can be the multiple spot welding, and suitable adjustment can be done according to the difference of coiling, lamination mode in its position.
After utmost point group had designed, with encapsulating behind the packaging film, the battery that forms after the fluid injection as shown in Figure 4.The anode ear 11 of battery, the negative electrode lug 12 of battery, packaging film 13.
