Abstract

The present disclosure provides a composite hydrophilic membrane electrode, a membrane capacitor cell, a preparation method and use thereof. The method for preparing the composite hydrophilic membrane electrode includes: mixing Li₂CO₃ with TiO₂ evenly to obtain a mixture, and baking the mixture to obtain a Li₂TiO₃ precursor; mixing the Li₂TiO₃ precursor with graphene oxide evenly to obtain a Li₂TiO₃/graphene oxide composite material; calcining the Li₂TiO₃/graphene oxide composite material to obtain a Li₂TiO₃/reduced graphene oxide composite material; modifying the Li₂TiO₃/reduced graphene oxide composite material with tannic acid to obtain a modified active electrode material; and mixing the modified active electrode material with a solvent to obtain an active electrode slurry, applying the active electrode slurry onto a titanium plate, and baking the active electrode slurry to obtain the composite hydrophilic membrane electrode.
