It is with symmetrial structure of both sides, the metal density nearing the copper theoretical density, very low surface pofile, and high elongation and tensisle strength; comparing with the single-matte and double-matte ED Copper Foils, when it adheres with the cathode materials, the contact area will increase dramatically, it can distincly reduce the contact resistance betweem the cathode current collector and the cathode material; the cathode current collector of the foil also has the excellent resistance of the cold and heat expansion, it can obviously increase the service life of the batteries.
