NOVELTY - Preparing fibrous electrodes by active printing, comprises (i) preparing electrode active material, the conductive agent and the binder into a slurry with a certain viscosity; (ii) adding slurry into a syringe, 3D printing and coating on a coaxially rotating conductive fiber substrate, and obtaining wet fibrous electrodes with different loads by adjusting the injection speed, rotation speed and stepping speed and drying to obtain fibrous electrodes. USE - The method is useful for preparing fibrous electrodes by active printing. ADVANTAGE - The obtained fibrous electrode has high strength, good conductivity, high active load, good energy storage capacity and bending resistance.
