Abstract
An electrochemical separation membrane and the manufacturing method thereof are disclosed. The method includes: a polymer solution preparing step to mix a polymer material, solvent and ceramic precursors thoroughly to form a polymer solution, wherein the polymer material and the ceramic precursors are dissolved uniformly in the solvent; a coating step to coat the polymer solution on a porous base material; a hydrolysis step to cause the porous base material coated with the polymer solution to contact an aqueous solution to hydrolyze the ceramic precursor into ceramic particles; and a drying step to remove the water and the solvent from the porous base material and in order to form the electrochemical separation membrane. The electrochemical separation membrane made of this method have better ion conductivity, interface stability and thermal stability based on the ceramic particles.
