Power battery as one of the three major components of electric vehicles (battery, motor, electric control), is the power source of the entire vehicle system, has been regarded as a landmark technology for the development of electric vehicles, its performance is directly related to the range of travel. Current energy vehicles equipped with two mainstream power battery as following, 1) ternary lithium battery features: high energy density ratio, fast charging, energy storage, long range, but high thermal management requirements, cycle repeat charge and discharge times are relatively small. 2) lithium iron phosphate features: better thermal management safety, cycle repeat charge and discharge times are more, long service life, but longer charging time, range capacity is relatively short. The copper foil for (EV) power battery negative electrode is specially developed by CIVEN METAL for power battery, which has the characteristics of high purity, good denseness, high precision and easy coating.High-precision RA Copper Foil [BCF] Battery ED Copper Foil *Note: All the above products can be found in other categories of our website, and customers can choose according to the actual application requirements.
