Abstract
The utility model relates to a negative pole ear structure of lithium cell, the compound area of fe -Cu or the compound area of fe -Cu -Fe of plating ni for the surface. This kind of negative pole ear structure of lithium cell, easy welding, the handling ease, production efficiency is higher, internal resistance simultaneously is relatively low, still has the higher advantage of price / performance ratio in addition.
Description
Technical field
The utility model relates to a kind of negative electrode lug structure of lithium battery, belongs to lithium battery production technical field.
Background technology
On usual market, the basal body structure of cathode of lithium battery ear is divided into following several: 1, pure nickel structure, such negative electrode lug often cost costly, cost is too high, and welding performance is poor; 2, nickel-plated steel structure, such negative electrode lug resistance is relatively high, and loss is too large, but welding performance is slightly better relatively; 3, nickel-copper compound structure; 4, nickel-copper-nickel composite construction; The negative electrode lug that nickel-copper meets structure and nickel-copper-nickel composite construction belongs to relatively high-end product usually, and cost is also higher, and welding performance is also poor simultaneously.Consider negative electrode lug or the welding comparatively difficulty of these types, make difficulty of processing comparatively large, production efficiency reduces, or internal resistance is larger.
Therefore find a kind of negative electrode lug structure of comparatively easily welding, internal resistance is simultaneously little, is obviously more desirable selection.
Utility model content
The purpose of this utility model is the problem overcoming above-mentioned prior art, and provide a kind of negative electrode lug structure of comparatively easily welding, it is convenient to processing, and production efficiency is higher, and internal resistance is simultaneously less.
The purpose of this utility model is achieved through the following technical solutions:
A negative electrode lug structure for lithium battery is Fe-Cu composite band or the Fe-Cu-Fe composite band of plated surface Ni.
In order to be welded to connect performance during more outstanding use, preferably, the negative electrode lug structure of this lithium battery is the Fe-Cu-Fe composite band of plated surface Ni.
Contrast these negative electrode lug structures existing on market: the negative electrode lug structure of lithium battery described in the utility model also has the higher advantage of cost performance simultaneously.
The negative electrode lug structure of lithium battery described in the utility model is Fe-Cu composite band or the Fe-Cu-Fe composite band of plated surface Ni.The negative electrode lug structure of this lithium battery, more easily welds, and be convenient to processing, production efficiency is higher; Internal resistance is simultaneously relatively low, also has the higher advantage of cost performance in addition.
Accompanying drawing explanation
Fig. 1 is the structural representation of negative electrode lug structure in embodiment one of lithium battery described in the utility model;
Fig. 2 is the structural representation of negative electrode lug structure in embodiment two of lithium battery described in the utility model.
Embodiment
