What is Nickel-iron battery?
The '''nickel–iron battery''' (NiFe battery) are [[Battery|batteries]] made of [[iron]] and [[nickel]] oxide hydroxide, with a [[potassium hydroxide]] electrolyte. They are very strong, and do not break easily. They can last for more than 20 years. They are slow to charge. They are often used on [[train]]s. They are similar to the [[nickel cadmium battery]], but using iron instead of [[Poison|toxic]] [[cadmium]]. The voltage is 1.2 volts per cell, the same as the nickel cadmium battery. Nickel-iron batteries are very durable. They can be charged many times. They are often associated with [[Thomas Edison]], although he did not invent this type of battery. Edison's company manufactured the batteries until the early 1970s. Today they are made by several [[China|Chinese]] companies. They are often used in applications where a very long service life is required, such as large off-grid solar power systems. ==Related pages== *[[Nickel–zinc battery]] - a similar battery with a higher capacity and higher voltage, but a shorter lifespan {{stub}} [[Category:Iron]] [[Category:Batteries]]
