Embodiment 1
[0032]A vanadium battery with multi-layer ionic membrane composite electrode comprises electrolytic solution and an ionic membrane placed in the electrolytic solution. Electrodes are respectively arranged on both sides of the ionic membrane, and the bottom of the electrode is inserted into the electrolytic solution.
[0033] The ionic membrane is a multi-layer material. A silicon dioxide layer with a thickness of 300nm is electroplated on the lower layer of the pretreated perfluorosulfonic acid proton membrane, and then a layer of perfluorosulfonic acid proton membrane two is electroplated on the lower layer of the silicon dioxide layer. A layer of diethylene glycol diacrylate phthalate is electroplated on the upper surface of the perfluorosulfonic acid proton membrane one, and a sodium alginate diester layer is electroplated on the lower surface of the perfluorosulfonic acid proton membrane two. into an ionic membrane with a multilayer structure.
