▎ 摘　　要

NOVELTY - Porous electrode material, prepared by reacting isocyanate component and combined white material, is claimed. The combination white material comprises 70-95 wt.%, preferably 75-90 wt.% polyol component, 1-25 wt.%, preferably 2-24 wt.% graphene oxide, and 1-10 wt.%, preferably 2-8 wt.% covalent organic framework material. The mass ratio of the isocyanate component and the combined white material component is 0.5-2:1, preferably 1-1.6:1. USE - Porous electrode material. ADVANTAGE - The porous electrode material has high porosity, large specific surface area, high specific capacitance, excellent electrochemical cycle life, high one-step foaming efficiency, high selectivity range, high structure diversity and designability, and excellent electrical performance. The method is simple, easy to operate, and provides the electrode material with high magnification performance and cycle stability. The electrode material can be used for super capacitor electrode material, as the electrode has a higher specific capacitor, good magnification performance, good polarity, good compatibility with the polyol component, and introduces heterogeneous atom for the final carbon material, redox reaction of nitrogen/boron functional group in the charging and discharging process increases the pseudo-capacitor of the carbon material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of porous electrode material.
