| Abstract: | The effect of La content on the electrochemical properties of uncoated La xMm 1-x (NiCoMnAl) 5 hydrogen storage alloy has been studied. The results indicate that with the increase of La content in the alloy, the activation property, discharge capacity and high rate dischargeability increase. In addition, its charge retention ratio increase first and then decrease, while its charge discharge cycle life decrease. The highest discharge capacity (in 1C) of this alloy is more than 300 mAh/g. |
