High Precision Battery Aluminum Foil for Lithium Ion Battery

Short Description:

The battery Aluminum foil is become more and more popular in the new energy in the past 8 years all over the world ,especially in China and Europe. Battery aluminum foil is used for the positive electrode in lithium-ion rechargeable battery.It asks for very high requirements for the surface .the usual alloy is 1060 ,1070 and 1235 .

The characteristics for the Battery aluminum foil :

·    Excels in foil flexibility
Due to its flexibility, this foil is resistant to the expansion and contraction of battery at the time of charge/discharge.
·    Good in smoothness on either side
The active material to provide the functionality of battery can be applied uniformly.
·    Small in foil thickness variation
Due to its small thickness variation, the coating thickness variation of active material can be suppressed.
To raise the output power, the HEV battery has a thinner active material layer than the commercial batteries.
The smaller the foil thickness variation, the smaller can be made the thickness variation of the active material.
This advantageous property of our product has been highly appreciated by every automotive battery manufacturers, and is often a decisive factor in accepting orders.
