This study presents a highly conductive paper for energy-storage devices, created by conformally coating single-walled carbon nanotubes (CNTs) and silver nanowires (Ag NWs) onto commercial paper using simple solution processes. The resulting conductive paper has a sheet resistance as low as 1 Ω/sq, making it highly conductive and suitable for use in supercapacitors and lithium-ion batteries. Compared to plastics, paper substrates offer better film adhesion, simpler coating processes, and lower costs. Supercapacitors based on CNT-conductive paper exhibit excellent performance, with a specific capacitance of 200 F/g, a specific energy of 30–47 Wh/kg, a specific power of 200,000 W/kg, and a stable cycling life over 40,000 cycles. Even when considering the weight of all dead components, a specific energy of 7.5 Wh/kg is achieved. The conductive paper can also serve as a lightweight current collector in lithium-ion batteries, replacing traditional metallic counterparts. The study demonstrates that conductive paper can be a highly scalable and low-cost solution for high-performance energy storage devices. The paper's unique properties, such as high solvent absorption and strong binding with nanomaterials, allow for easy and scalable coating procedures. The conductive paper is also mechanically robust, with excellent flexibility and stability against damage. It has been successfully used as an electrode in supercapacitors and as a current collector in lithium-ion batteries. The study also shows that the conductive paper is chemically stable in electrolytes, with no detectable disintegration after prolonged exposure. The results indicate that conductive paper can be a promising material for future energy storage applications.This study presents a highly conductive paper for energy-storage devices, created by conformally coating single-walled carbon nanotubes (CNTs) and silver nanowires (Ag NWs) onto commercial paper using simple solution processes.
