The invention relates to a porous epoxy resin structure electrolyte and a preparation method and application thereof. The method comprises the following steps: mixing and uniformly stirring epoxy resin and a pore-foaming agent, then adding a curing agent and uniformly stirring to obtain a mixture; defoaming the mixture, and curing in a mold to obtain a cured product; demolding the cured product, soaking the cured product in water, and freeze-drying the cured product to obtain a structural electrolyte precursor; and soaking the structural electrolyte precursor in an electrolyte solution for activation to prepare the porous epoxy resin structural electrolyte. A reaction-induced phase separation method is used, matrix resin suitable for a composite material is used as a matrix, a poor solvent not participating in a curing reaction is used as a pore-foaming agent, and carbon nanofibers or Zn-Co bimetallic oxide modified carbon nanofibers are added, so that a phase separation interface is obviously improved; the s
