Polymer carbon foil for solid capacitors is a functional cathode foil material used in solid aluminum electrolytic capacitors. It typically uses aluminum foil or etched aluminum foil as the substrate, with a carbon nanotube, graphite, or composite conductive carbon layer formed on the surface. It is not a solid capacitor itself, but an upstream key material used inside solid capacitors. Its main function is to improve the interfacial contact between aluminum foil and conductive polymer solid electrolyte, reduce equivalent series resistance, and enhance conductivity, adhesion, bending resistance, and capacitor service life. Compared with ordinary carbon foil, this product places greater emphasis on capacitor application compatibility, requiring carbon layer uniformity, interfacial bonding strength, thickness consistency, impurity control, and electrochemical stability to meet the manufacturing requirements of solid capacitors.

Its upstream mainly includes high-purity aluminum foil, etched foil, carbon nanotube, graphite, conductive carbon black, dispersant, binder system, as well as coating, drying, calendering, slitting, and other processing steps. Among these, substrate foil quality, conductive carbon layer formulation, and coating uniformity are the key factors affecting product performance and cost. The downstream market mainly serves manufacturers of solid aluminum electrolytic capacitor and hybrid aluminum electrolytic capacitor, with end-use applications in consumer electronic, industrial power supply, automotive electronic, communication equipment, server power supply, and other high-frequency, low-ESR power filtering scenarios. With the increasing demand for miniaturization, high-frequency performance, and high reliability in electronic device, the value of this type of carbon foil material in reducing ESR, improving capacitor stability, and extending service life is becoming increasingly significant.
