Abstract: 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.
