Layer-by-Layer Electrode Fabrication for Improved Performance of Porous Polyimide-Based Supercapacitors.

ABSTRACT: Nanoporous polymers are becoming increasingly interesting materials for electrochemical applications, as their large surface areas with redox-active sites allow efficient adsorption and diffusion of ions. However, their limited electrical conductivity remains a major obstacle in practical applications. The conventional approach that alleviates this problem is the hybridisation of the polymer with carbon-based additives, but this directly prevents the utilisation of the maximum capacity of the polymers. Here, we report a layer-by-layer fabrication technique where we separated the active (porous polymer, top) layer and the conductive (carbon, bottom) layer and used these "layered" electrodes in a supercapacitor (SC). Through this approach, direct contact with the electrolyte and polymer mate
