Electrochemical performance of NAFION coated electrodes of HCSed MgNi based composite hydride
Аннотация
Mg based hydride electrodes in alkaline solution were protected by coating them with hydrogen-permeable NAFION membranes. The electrodes were fabricated by using Mg based hydrides synthesized by hydriding combustion (HC) technique. The hydriding combustion synthesized (HCSed) powders were further ball-milled and fabricated into pellet-type electrodes with and without NAFION coating. The ball-milled HCSed powder showed nearly three times higher surface area (∼15 m2 g−1) than that of the as-HC synthesized powder, and thus provided higher discharge capacity. Furthermore, the ball-milled HCSed electrode with NAFION coating exhibited nearly 400% higher discharge capacity (713 mAh g−1) than that of the un-coated as-HCSed electrode.
