Polymer carbon foil is specifically designed for solid state capacitors . Its material is made by carbon nanotubes coating on the corrosion of aluminum foil, using carbon tube or tubes of microporous, to increase the adhesion between the aluminum foil and conductive polymer and its intensity of crooked, and  reduce the resistance caused by poor contact, then increase service life.

1.Improve the surface tension of aluminum foil and increase adhesion of aluminum foil and conductive polymer
2.Reduce the interfacial resistance and battery internal resistance.
3.Protect current collector and prevent oxidation or corrosion from the aluminum foil surface.
4.Reduce the calorific value, increase the safety of the battery.
5.Improve stability and consistency and promote cycling life.
