Carbon coated aluminum foil is kind of the aluminum foil that evenly coated with current-conducting nano-graphite and carbon particle. The carbon coated aluminum foil owns an excellent static electric conductivity, it can collect the micro-current of active substance, it is not only to significantly reduce the contact resistance between the positive / negative electrode material and the collector, but also increase the adhesive ability between both of them, thus to reduce the amount of binder and improve overall performance of the battery.
