GY-GA-F-AL-1 Graphene Coated Aluminum Foil Current Collector
GY-GA-F-AL-1 is an aluminum foil current collector coated with graphene. Its 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 supercells.
Description
Intro
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 the charge/discharge rate and cycle life of a battery. Its 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 supercells.
