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.
