3OZ Thin Electrolytic copper foil rolls for lithium ion battery
Copper foil for lithium ion battery
The nominal thickness 9-70 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.
