Abstract
In his paper, the effect of fluorination treatment on the capacity and activity of hydrogen storage alloy was studied. Cyclic charging-discharging results showed that fluorination treatment could improve capacity and activity of hydrogen storage alloy obviously. SEM observing results showed fluorination treatment could remove oxide film from grain surface, thus promoted activation and capacity. Electrochemical impedance spectra test proved that fluorination treatment increased conductivity of alloy and decreased electrochemical reaction resistant, which improved the discharge capacity and the activity of hydrogen storage alloy.
