A study on vanadium crossover using pore filling membranes for vanadium redox flow batteries |
초록 |
Novel pore-filling membranes with low vanadium crossover were developed for the application to a vanadium redox flow battery. The polymer electrolytes consisting of the whole hydrocarbon materials were introduced into porous hydrocarbon substrates and crosslink-polymerized by radical polymerization in this work. The thickness of the prepared membranes was controlled between 20 and 25 micrometers to extremely lower membrane resistances. Finally, film-like polymer electrolyte membranes were prepared. The prepared pore-filling membranes are able to drastically decrease vanadium co-ion crossover through the membrane because the porous substrate suppresses a swelling factor of highly functionalized electrolytes in water media such as liquid phase operation conditions. The physico-chemical properties of the prepared membranes such as swelling behavior, membrane area resistance, vanadium co-ion crossover were investigated in correlation with the electrolyte composition. Also the thermal and the structural property of the prepared pore-filling membranes were evaluated. |
