NOVELTY - Water-based proton battery electrode based on aza-conjugated porous polymer comprises an aza-conjugated porous polymer as a proton or hydrated proton storage material, which achieve proton or hydration in a proton-containing aqueous electrolyte solution electrochemical insertion and extraction of hydrated protons. USE - Water-based proton battery electrode based on aza-conjugated porous polymer. ADVANTAGE - The electrode achieves electrochemical insertion and separation of protons or hydrated protons at highly safe protons-containing aqueous solutions. It utilizes reversible redox-storage proton or hydrated proton of a large number of aromatic aza- sites enriched in the azaconjugated porous polymer. The porous structure of the azaconjugated porous polymer and high specific surface area, not only can realize stable de-embedding of proton with large volume, but also can provide fast ion transport channel and expose more ion storage sites.
