Battery Aluminum Foil is Used for Electric Vehicle Battery Shell

Battery Foil

The electronic aluminum foil,l.e.aluminum foil for lithium battery.Is called battery aluminum foil.It is used as the current collector and tab.Generally,the lithium-ion battery trade uses the rolling aluminum foil as positive pole of collector.The foil's thickness ranges is from 10 to 50 microns.The pure aluminum foils for common lithium batteries have such alloy designations as 1070.1060.1050,1145 and 1235.as well as such temper as O.H14.H24.H22 and H18.The battery aluminum foil is used widely.And it is always used for the production of power battery core material for handset,other electronic products,electric motor car,electric tools.electric bus etc.

Battery aluminum foil is made of 1235 pure aluminum series of alloy.with the features of beautiful appearance,high-precision surface,and flat profile etc.The thickness range of common specifcations is 0.012-0.020mm.The width can be selected as per the manufacturer's production equipment requirement.The lithium batteries of handset and other electronic products are generally 0.012-0.016mm thick,but the power batteries of electric motor car and electric bus are 0.014-0.020mm thick.

Aluminum alloy foil for electronics is widely applied in consumer battery.power battery and electronic product,etc.

3003 Aluminum Foil Applications

1. Electric vehicle battery cells

2. lithium power battery

3. Lithium-ion supercapacitor/batteries

4. Consumer battey

3003 Aluminum Foil Character:

• Stable ingredients,less impurities,high purity and excellent conductivity.
• Its high surface and fine pattern are beneficial for subsequent processing such as coating.stripping and piece production.
• Its thickness is uniform and tolerance is within the scope of 2%,which is good for controlling gram weight of base material of battery cathode.
• Excellent profile

Serious Advantages for the Application of 3003 Aluminum Foil in Lithium Battery:

1. Improve the surface tension, and increase the adhesion between the aluminium foil and the active material.

2. Decrease the using amount of binder for the electrode ,enhance energy density of the battery ,and lower the cost of the electrode production

3. Protect the AI current collector from surface corrosion and oxidation.

4. Reduce interface resistance and internal resistance of the cell.

5. Decrease polarization and improve the rate capability and specific capacity of the electrode material

6. Improve the production stability and reproducibility ,and raise the pass rate of the cell

7. Mitigate exothermic reactions and enhance the battery safety

8. Increase the consistency and cycling life of the cell,and lower the cost of the production.
