The invention discloses a method for preparing a titanium-based super capacitor membrane electrode, which is characterized by comprising the following steps: 1) spraying sands; 2) removing oil; 3) carrying out acid-washing and etching; 4) adding an interlayer; and 5) electrochemically depositing an active MnO2 coating. The method has the advantages that: the interlayer of the prepared electrode is firmly combined with the matrix of the electrode, and the MnO2 coating is provided with a plurality of micropores which facilitate exchanging active substances, and is not easy to fall off; the electrode has good cyclical stability, and is high in specific capacity, long in service life and good in adhesion of the coating; and the electrolyte is neutral Na2SO4 solution, which is convenient to promote and apply in industry.
