Lithium Ion Battery Shell Aluminum Foil From China
Details ：
Zhejiang Tech Co Ltd is one of the leader for the battery aluminum foil in China .
We have researched and produce the Lithium Battery Aluminum Foil eight years already and now we cooperate several new energy automobile factories here and the demand of that is sharply risen in the past 4 years.
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.
