Abstract： |
This invention relates to proton exchange complex film used in vanadium oxidation-reduction battery and its process method, wherein the film uses the inorganic nanometer materials polyvinylidene fluoride as base part and then introduces organic acid with sulfonic acid root through autopolymer to get aim product. The process method to make film with good proton conductivity property and good isolation vanadium ion transparency and chemical stability with simple process and low film cost. The film conducting rate can achieve 10 to 2 S/cm and the vanadium ion transparency rate is as 10 to 7 cm2/min. |
