제목 Performance evaluation by silica content of sPPO / silica composite membrane for the prevention of cross contamination
초록 Recently, demand for electricity is nearing the limits of supply in accordance with the increase. As a means to solve this problem, such as the Smart Grid and the ESS has been introduced. Among them, vanadium redox flow batteries can be re-used in the electrolytic solution, and capacity enhancement and maintenance, the maintenance has a highly competitive as to facilitate ESS. But the biggest problem is receiving attention from the redox flow battery capacity is reduced and lifetime degradation due to cross contamination.
In this study, in order to prevent cross contamination in the vanadium redox flow battery, sulfonated silica was dispersed in sPPO solution. and it was prepared by casting a solution of sPPO membrane. By changing the amount of silica was to evaluate the performance of the produced silica/sPPO composite membrane. These membranes for dimensional change, conductivity, impedance, the change in performance was observed over a silica content in accordance with the charge/ discharge test.
