How Does a NiMH Battery Work?
Background NiMH or Nickel-Metal Hydride batteries are a type of rechargeable battery. They are used for a variety of purposes ranging from digital cameras to hybrid vehicles and industrial applications. The popularity of these batteries has grown in recent years as concerns over the environmental impact of toxic components and interest in recycling have increased. Most NiMH batteries can be recharged several hundred times over the course of its life. They are also subject to very little decline in the overall power output provided after they are charged. Batteries Batteries are self contained units that use chemical reactions to produce electricity. Most batteries have a four-component design. There is a positive electrode, negative electrode, an electrolyte and a separator. In a NiMH battery, the positive electrode is typically composed of nickel hydroxide, hence the name Nickel-Metal Hydride. The negative electrode is typically made of a metal hydride material, but the metals used va
