Molybdenum effect on the kinetic behavior of a metal hydride electrode

The replacement of manganese by molybdenum, in the intermediate concentration tested (2% w/w) has a positive effect. This alloy presents the greatest discharge capacity, the closest potential to system equilibrium potential and therefore the lowest overpotentials. This alloy also has the best behavior for high-rate dischargeability and in concordance, the lowest charge transfer resistance. This improvement is thought to be due to an increase in the active area.
