Example Embodiment
[0017] Specific embodiment 1: The preparation method of a metal oxide / activated carbon fiber composite electrode material with controllable morphology in this embodiment is carried out according to the following steps:
[0018] 1. Preparation of polyacrylonitrile fiber: add nitrate to N,N-dimethylformamide, ultrasonicate until the nitrate dissolves, then add polyacrylonitrile to the reaction system, and stir at room temperature for 6d~ 12d, obtain a polyacrylonitrile spinning solution; use an electrospinning device to take 5mL to 20mL of polyacrylonitrile spinning solution, control the pressure at the end of the micro-injection pump to be 80mmHg to 100mmHg, and the flow rate of the spinning solution to be 1mL / h to 1.5mL / h h, using aluminum foil as the receiving screen, electrospinning is carried out under the conditions that the receiving distance is 20cm~25cm, the output voltage is 18kV~22kV, the air humidity is 0~40%, and the diameter of the spinneret is 0.4mm~0.6mm, to obtai...
Example Embodiment
