Abstract: The invention discloses an aramid fiber electrode and a preparation method thereof. Silver nanoparticles, carbon nanotubes and polypyrrole were sequentially coated on the surface of the aramid fiber by chemical bonding, to prepare an aramid fiber electrode, two aramid fiber electrodes were wound with an electrolyte to obtain an aramid fiber electrochemical capacitor. Compared with the polymer fiber electrochemical capacitor prepared in the prior art, the aramid fiber electrochemical capacitor provided by the present invention has both high specific capacitance, high energy density, high mechanical performance, high stability, good flexibility and wearability. And other characteristics; the preparation method is controllable and suitable for large-scale applications.
