Graphene coated aluminum foil for supercapacitor/power battery

超级电容/动力电池用石墨烯涂层铝箔

(Graphene coated aluminum foil for supercapacitor/power battery)


A1 layer

Etching layer

Graphene layer


Nano-conductive graphene coating aluminum foil smears the graphene on the etching foil evenly, which can provide excellent static conductivity and micro-current to collect active substances. In this way, it greatly reduces the resistant between the positive/negative materials and the collectors, and upgrades their adhesion towards each other, therefore, the entire function of the battery is extremely improved result from it.


Product feature

•    Improve the surface tension, and increase the adhesion for the aluminum foil and the electroactive material.
•    Reduce the use of binder in electrode, uplevel the actual surface area of the battery.
•    Reduce the interfacial resistance and reduce battery internal resistance.
•    Protect current collector, prevent surface oxidation or corrosion of the aluminum foil.
•    Reduce the calorific value, and increase the safety of the battery.
•    Improve stability and consistency and promote cycling life.
