Mode be combined.
In a preferred embodiment of the present invention, the gross thickness of the aluminium foil and Copper Foil accounts for the 1/ of the aluminum base plate thickness
7~1/10.
In a preferred embodiment of the present invention, the ratio between thickness of the aluminium foil and Copper Foil is 1：2~3.
In order to solve the above technical problems, another technical solution used in the present invention is：A kind of corrosion-resistant battery aluminium is provided
The preparation method of shell, comprises the following steps：
（1）Prepare aluminum base plate：The soft state aluminium sheet for using thickness thicker is substrate；
（2）Prepare aluminium foil and Copper Foil composite plate：The aluminium foil and Copper Foil are first produced into rolling embryo, Ran Houzai through explosion composite method
It is rolled into composite plate；
（3）Prepare aluminum hull sheet material：By step（2）The aluminium foil one side of the composite plate of middle preparation is attached to step（1）The aluminium of middle preparation
On substrate processed, using it is cold rolling it is compound by the way of continuous rolling compound；
（4）Drawing and forming：By step（3）The composite plate of middle preparation is prepared into the aluminum hull through cold drawn stretching process.
The beneficial effects of the invention are as follows：A kind of preparation method of corrosion-resistant electrokinetic cell aluminum hull of the present invention, it passes through twice
Rolling mill practice effectively prevents contact of the lithium battery with aluminium casing in the basic internal Rolling compund aluminium foil of aluminum and Copper Foil, so that
Suppress or delay the corrosion reaction in housing, improve the corrosion resistance of aluminum hull, the Corrosion Protection to improving aluminum hull has weight
The meaning wanted, practicality is stronger, wide market.
Brief description of the drawings
Fig. 1 is a kind of structural representation of corrosion-resistant electrokinetic cell aluminum hull housing of the present invention；
The mark of each part is as follows in accompanying drawing：1. aluminum hull housing, 11. aluminum base plates, 12. aluminium foils, 13. Copper Foils.
Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 is referred to, the embodiment of the present invention includes：
Embodiment 1
A kind of corrosion-resistant electrokinetic cell aluminum hull, including：Aluminum hull body 1, the aluminum hull body includes ecto-entad clad aluminum successively
Substrate processed 11, aluminium foil 12 and Copper Foil 13；Wherein, the gross thickness of the aluminium foil 12 and Copper Foil 3 accounts for the thickness of the aluminum base plate 11
1/15~1/20；The ratio between thickness of the aluminium foil 12 and Copper Foil 13 is 1：2~3.
It is combined by the way of cold rolling forging is closed between above-mentioned aluminium foil 12 and aluminum base plate 11, is adopted between Copper Foil 13 and aluminium foil 12
It is combined with the mode of blast Rolling compund.
The preparation method of above-mentioned corrosion-resistant battery aluminum shell, comprises the following steps that：
（1）Prepare aluminum base plate：The soft state aluminium sheet for using thickness thicker is substrate；
（2）Prepare aluminium foil and Copper Foil composite plate：The aluminium foil and Copper Foil are first produced into rolling embryo, Ran Houzai through explosion composite method
It is rolled into composite plate；
（3）Prepare aluminum hull sheet material：By step（2）The aluminium foil one side of the composite plate of middle preparation is attached to step（1）The aluminium of middle preparation
On substrate processed, using it is cold rolling it is compound by the way of continuous rolling compound；
