Advantage of Double shiny Lithium battery Copper Foil Application:

Compared with single-sided, double-sided MAO lithium electricity copper foil, the anode materials and adhesive, a doubling of contact area, can significantly reduce the negative fluid and anode materials, the contact resistance between the increase of lithium ion battery anode plate structure symmetry.

At the same time, the double light lithium electricity copper foil has good resistance to heat and cold expansion performance, battery negative pole piece in the process of charging and discharging is not easy to fracture, can prolong the service life of the battery.
