Solid-state metal hydride batteries using ZrO2·nH2O as an electrolyte

Solid-state metal hydride batteries using ZrO2·nH2O as an electrolyte ZrO2·1.5H2O or ZrO2·1.5H2O-KOH composite was used as an electrolyte in order to develop a solid-state nickel-metal hydride battery. The battery using the ZrO2·1.5H2O-KOH composite had rechargeability, but had a very low discharge efficiency, even at low current density. However, the performance of the battery was prominently improved by enlarging the electrode-electrolyte interface area. The resultant battery exhibited the remarkably longer cycle life, the higher discharge efficiency, and the lower polarization: it was able to operate over 150 cycles at 10 mA/g alloy. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

ZrO2·1.5H2O or ZrO2·1.5H2O-KOH composite was used as an electrolyte in order to develop a solid-state nickel-metal hydride battery. The battery using the ZrO2·1.5H2O-KOH composite had rechargeability, but had a very low discharge efficiency, even at low current density. However, the performance of the battery was prominently improved by enlarging the electrode-electrolyte interface area. The resultant battery exhibited the remarkably longer cycle life, the higher discharge efficiency, and the lower polarization: it was able to operate over 150 cycles at 10 mA/g alloy.
