Nickel-iron BatteryThe nickel-iron battery is a storage battery having a nickel oxide cathode and an iron anode, with an electrolyte of potassium hydroxide. The nominal cell voltage is 1.2V. The battery was developed by Thomas Edison in 1901, and used as the energy source for electric vehicles, such as the Detroit Electric. The main advantage over nickel-cadmium was cost, but due to the poorer efficiency of the charging reaction and more pronounced formation of hydrogen (gassing), the nickel-iron technology soon become less relevant. Edison's batteries were made from about 1903 to 1940 if I recall correctly. They were quite profitable for the company. Edison was disappointed that his battery was not adopted for starting ICEs and that electric vehicles went out of production only a few years after his battery was introduced. The battery enjoyed wide use for railroad signalling and standby power applications.
