碩士 === 長庚大學 === 化工與材料工程學系 === 102 === Renewable energy used in smart grid development, large-scale energy storage technology developed by the attention. All vanadium redox flow battery (VRFB) is a mature technology and close to commercialization. VRB is divided into three core technologies: Proton exchange Membrane, Vanadium electrolyte, Carbon felt. But among the three vanadium electrolyte technology costs higher. If it want to increase the total storage capacity of the battery and reduce equipment costs, to find suitable formulations are particularly important. Positive vanadium electrolyte has many technical problems. In this experiment, the inorganic salt is NaCl, KCl, NH4Cl is added to the electrolytic solution of vanadium substituted difference between the mixed acid electrolyte. Research on the relationship between inorganic salts and V (V) / V (IV) and between the electrochemical test, UV-vis qualitative and quantitative analysis of the test. To find the appropriate ratio of vanadium electrolysis, the electrolyte can be done to improve the positive-electrode current technology problems.
