Nickel-iron batteries have less impact on the environment because nickel-cadmium batteries don't contain cadmium, which is considered a hazardous material. The overall call reaction for a nickel-iron cell is:
2 NiO(OH)(s) + 2 H2O(l) + Fe(s) → 2 Ni(OH)2(s) + Fe(OH)2(s)
Provide the anode half-reaction.
