NOVELTY - Hydrophilic modification of manganese ion sieve electrically controlled lithium extraction membrane electrode surface comprises (i) mixing the manganese ion sieve, agglomerant, conductive agent and the organic solvent to obtain the casting solution; (ii) coating the casting liquid on the electrode base material and removing part of organic solvent; and (iii) adding an organic surface modifying agent into the surface of the electrode base material and heating. USE - The method is useful for hydrophilic modification of a manganese- ion sieve electrically controlled lithium extraction membrane electrode surface is useful in battery. ADVANTAGE - The method: controls film electrode surface roughness and hydrophilicity; and modifies the surface of membrane electrode from hydrophobic electrode to surface of hydrophilic electrode to greatly improve the lithium embedding speed and capacity.
