Abstract

The utility model relates to the field of a battery, particularly to an aluminum tab structure on the battery, which comprises a battery cell, an anode and a cathode, wherein the anode adopts a nickel electroplated layer structure arranged outside the aluminum tab. As the aluminum tab structure requiring no nickel conversion can be processed in batch array by array, the labor hour is greatly shortened, the welding is eliminated as well, so as to avoid the welding penetration, and the dropping-off phenomenon during the processing is avoided, and meanwhile the subsequent processing of the battery cell is not influenced.

Description

Need not change the aluminium pole ears structure of nickel

Technical field

The utility model relates to field of batteries, especially a kind of aluminium pole ears structure on the battery.

Background technology

As depicted in figs. 1 and 2, aluminium strip (thickness 0.1mm) is adopted at the aluminium pole ears CPP glue two ends of anodal usefulness, one end is welded on the positive plate, be honored as a queen carrying out the top side, expose CPP glue about 0.5mm and add aluminium matter lug 9 (nickel strap of perhaps having transferred in advance) about 4mm, be used to the nickel strap 8 of transferring herein, so that carry out next step processing.

2, there is defective in original structure:

1.. it is low manually to change the nickel operating efficiency;

2.. for the easy burn-through of narrow lug (wide 2mm and 2mm are following);

3.. come off easily in the following process process in the good back of welding in advance.

Summary of the invention

The purpose of this utility model provide a kind of high efficiency, can not burn-through and in the following process process aluminium pole ears structure that need not change nickel of difficult drop-off.

To achieve these goals, the utility model adopts following technical scheme:

It comprises an electric core and a both positive and negative polarity, and its improvement is: described just very aluminium pole ears is provided with a nickel electrodeposited coating structure outward.

Preferably, described positive pole is honored as a queen in the top side and is comprised cpp and nickel electrodeposited coating structure about 0.5mm.

The aluminium pole ears structure that need not change nickel of the present utility model is because can the row's of putting in order batch machining, and labor hour shortens greatly; Remove welding simultaneously, avoided burn-through; In the course of processing, avoid obscission, do not influenced electric core following process simultaneously.

Description of drawings

Fig. 1 is a schematic diagram before the existing aluminium pole ears structure processing;

Fig. 2 is an existing aluminium pole ears structure processing back schematic diagram;

Fig. 3 is the structural representation of the utility model embodiment.

Embodiment

As shown in Figure 2, it comprises an electric core 1, anodal 2 and negative pole 3, and described anodal 2 are provided with a nickel electrodeposited coating structure outward for aluminium pole ears.

In the present embodiment, described anodal 2 are honored as a queen in the top side comprises cpp and nickel electrodeposited coating structure about 0.5mm.

Its procedure of processing is:

1, the CPP aluminium pole ears contains the immersion of aluminium strip one end in the electrolytical solution of nickel salt when making, and immersion depth carries out as requested, and aluminium strip one end is connected an end (negative pole) of power supply, power positive end connects the pure nickel band by lead, regulate slide rheostat, open power supply, carry out electroplating processes.

2, CPP aluminium pole ears aluminium matter one end after will processing is welded on the positive plate, and the end after the electroplating processes exposes to outside the plastic-aluminum, is honored as a queen through the top side, exposes CPP glue about 0.5mm and adds and electroplate an end of handling.

The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.

Claims

1. the aluminium pole ears structure that need not change nickel, it comprises an electric core, positive pole and negative pole, it is characterized in that: described just very aluminium pole ears is provided with a nickel electrodeposited coating structure outward.

2. the aluminium pole ears structure that need not change nickel as claimed in claim 1 is characterized in that: described positive pole is honored as a queen in the top side and is comprised cpp (polychloroprene) and nickel electrodeposited coating structure about 0.5mm.
