A nickel-iron battery with roll-compacted iron electrodes

The performance of a 6 V/6 Ah, commercial size, nickel-iron battery with roll-compacted iron electrodes is reported in terms of its discharge characteristics and cycle-life data. The battery can withstand prolonged charge/discharge schedules with little deterioration in its performance. The effect of varying discharge rate and temperature on the performance of a 1.2 V/2.5 Ah nickel-iron cell is also examined.
