摘要: The effect of temperature on the performance a LaNi4.76Sn0.24 metal hydride electrode was investigated in range 0 to 50°C. showed maximum discharge capacity at 25°C. total resistance increases with decrease from 50°C 0°C. apparent activation enthalpies different states charge were determined by evaluating polarization temperatures. It found that enthalpy is an indicator relative reaction rate charge-transfer and hydrogen absorption.
