Abstract

The invention provides a three-dimensional structure multilevel-hole graphene electrode material and a preparation method thereof. The preparation method comprises the steps of 1) dispersing graphite oxide into an organic solvent to obtain a graphite oxide dispersion liquid, drying, and removing the organic solvent to obtain a graphite oxide powder after solvent treatment; 2) dispersing the graphite oxide powder after the solvent treatment, obtained in the step one, into water, adding a reducing agent, carrying out reaction for 0.5-3 hours at the temperature of 90-100 DEG C; and 3) adopting strong base, zinc chloride or carbon dioxide to carry out activation treatment on the graphene obtained in the step two, and preparing the three-dimensional structure multilevel-hole graphene electrode material.
