对不同冷却速度下制成的具有同一成分的贮氢合金做了电化学充放电循环实验，比较了它们的容量、电化学循环稳定性及放电电压性能高的冷却速度导致放电容量特别是大电流放电容量较大幅度下降，活化困难，放电电压也有所降低，但改善了合金的循环稳定性及放电电压平台特性．
Electrochemical charge and discharge cycle experiments were carried out on hydrogen storage alloys with the same composition made at different cooling rates. Their capacity, electrochemical cycle stability and discharge voltage were compared. High cooling rate led to high discharge capacity, especially high current Discharge capacity decreased significantly, activation difficulty, discharge voltage also decreased, but improved the cycle stability of the alloy and discharge voltage platform characteristics.
