Figure 1. Hybrid carbon redox-polymer-gel (C-RPG) ultra-capacitor concept.

Figure 1

(A) Schematic representation of the C-RPG electrode. The high surface-active carbon - CNT mat is flooded into a PTMA gel to generate the hybrid composite electrode. (B) SEM image of the C-RPG electrode. The layered morphology originates from the sequential deposition technique. Insets: optical micrographs of a dry PTMA pellet (top) and of a swelled C-RPG electrode (bottom). (C) Electrochemical response of the C-RPG and EDLC electrodes (charged and discharged at ~1C rate corresponding to 63 and 38 mA/g, respectively). The capacity is given per total mass of electrode. (D) Capacity and energy gain in C-RPG electrodes is as high as 170% upon incorporation of only 40% by weight PTMA.
