GY-GA-F-AL-1 is an aluminum foil current collector coated with graphene. Its excellent conductivity and 2-dimension layer structure can form a super thin conductive layer on the surface, decreasing the interface contact resistance and strengthen the adhesion, thus elevating its charge/discharge rate and cycle life of a battery. It general properties surpass carbon black and graphite coated foil, and can replace traditional aluminum foil & erosion foil. GY-GA-F-AL-1 can be applied to Li battery and other super cell.

Method & Notes
1. Directly used as current collector in Li battery or supper battery. 2. Accustomed to different coating methods with moisture under 30%. 3. Ultrasound electrode welding can level up the power by 10% better than common aluminum foil. 4. Product is prone to absorb moisture. Do not open until usage. When left, dry it in vacuum box at 40~60℃for 2 hours, then store it at room temperature.
