Preparation method of nanofiber-based porous composite electrode material

The invention relates to the technical field of preparation of electrode materials, and particularly discloses a preparation method of a nanofiber-based porous composite electrode material, and the method comprises the following steps: preparing an electrospinning solution, adding polytetrafluoroethylene, carrying out electrospinning, carrying out an ion implantation method, curing, cutting and assembling. The nanofibers are prepared by utilizing an electrospinning method, hydrogen ions are added into the nanofiber structure in cooperation with an ion implantation method so as to enhance the hydrogen storage capacity of the nanofibers, and in addition, lithium manganate is used as an active material and is used for increasing the embedded lithium ion capacity of the cobalt oxide nanowires, so that the hydrogen storage capacity of the cobalt oxide nanowires is improved. The carbon nano tube is used as a conductive additive for improving the conductivity of the cobalt oxide nanowire, so that the nanofiber-based
