Nickel–iron battery
The nickel–iron battery (NiFe battery) is a rechairgeable battery haein nickel(III) oxide-hydroxide positive plates an airn negative plates, wi an electrolyte o potassium hydroxide. The active materials are held in nickel-plated steel tubes or perforated pockets. It is a very robust battery which is tolerant o abuse, (overcharge, overdischarge, an short-circuiting) an can hae very lang life even if sae treatit.[6] It is eften uised in backup situations whaur it can be continuously charged an can last for mair nor 20 years. Due tae its law specific energy, poor charge retention, an heich cost o manufacture, ither types o rechairgeable batteries hae displaced the nickel–iron battery in maist applications.
 Nickel–iron batteries manufactured between 1972 and 1975 under the "Exide" brand originally developed in 1901 by Thomas Edison. | |
