Product Description

High Purity Double Sided Lithium Battery Copper Foil

 

 

Copper foil for lithium ion battery

 

The nominal thickness 8-20 μm for single-sided and double-sided wool as well as dedicated electrolyzed copper foil double-sided light lithium battery,the scope of product breadth is 100-1300mm,of which double-sided optical electrolyzed copper foil features that double-sided structure is symmetriacl, density of metal is close to copper theoretic density,surface profile degree is extremely low,extension rate and tensil strength are high. Compared with electrolyzed copper foil for single-side and doule-side wool lithium battery,as it is affixed with cathode material ,the touch area doubles,which reduces touch resistance between the cathode collectrors and the cathode materials to enhance symmetry of volume capacity and structure of the battery.meanwhile ,double side optical electrolyzed copper foil cathode collector has wonderful resistance cold and thermal expansion performance,which can obviously extend life of the battery.

99.9% Purity Red Rolled Electrodeposited Copper Foil

99.9% Purity Red Rolled Electrodeposited Copper Foil Description: Electrolytic copper foil is a foil-based form of copper with a thickness generally less than 80micron. A rolled foil is made by annealing and rolling the electrolytic copper uninterruptedly.The production process involves electrodepositing copper to a rolling drum and then again rolling it up. For the process of electrodeposition, high-grade copper is dissolved in acid to form a copper electrolyte. This copper
