Scalable 18650 aqueous-based supercapacitors are ideal as future energy storage technology due to their great safety, low cost, and environmental friendliness as well as high power density. Until now, there are no commercial aqueous-based supercapacitors due to the corrosion of metal current collectors. In this work, we have introduced a new concept using hydrophobicity of anti-corrosion graphite passivation layer coated on Al foil with high surface roughness leading to the lotus effect.
