nickel–iron accumulator

Physics

A secondary cell devised by Thomas Edison (1847–1931) having a positive plate of nickel oxide and a negative plate of iron both immersed in an electrolyte of potassium hydroxide. The reaction on discharge is

$2 NiOOH {.H}_{2} O + Fe \to 2 Ni {(OH)}_{2} + Fe {(OH)}_{2},$

the reverse occurring during charging. Each cell gives an e.m.f. of about 1.2 volts and produces about 100 kJ per kilogram during each discharge. The nickel–cadmium cell is a similar device with a negative cadmium electrode. It is often used as a dry cell. Compare lead–acid accumulator.
