A flexible electrode and a fabrication method therefor are provided. The flexible electrode is formed by mixing organic-soft-matrix with inorganic-hard-material. The inorganic-hard-material is composed of silicate lamellar blocks and electrochemically active materials. Each of the silicate lamellar blocks is formed by multiple stacked nano-scaled sheet-like silicate lamellae. The organic-soft-matrix includes conductive polymer and binder. The binder is water-soluble and ionically conductive. The flexible electrode has a floor-ramp like opened-perforated layer structure formed by hierarchically aggregated inorganic silicate lamellar blocks, and pores of the opened-perforated layer structure are filled with the organic-soft-matrix, so as to form a network channel structure having organic phase and inorganic phase interlaced with each other. The floor-ramp like opened-perforated layer structure composed of aggregated inorganic silicate lamellar blocks contributes to stiffness of the flexible electrode, and the conductive polymer and the binder in the organic-soft-matrix respectively form electron channels and ion channels in the flexible electrode.

Flexible electrode and fabrication method therefor

A conductive paper electrode includes a paper, a carbon powder layer, a graphite layer and a nanostructural layer. The carbon powder layer is positioned over the paper. The graphite layer is positioned over the carbon powder layer. The nanostructural layer is positioned over the graphite layer. An electrochemical capacitor includes two conductive paper electrodes and an electrolyte interposed therebetween.
