Nickel Metal Hydride
The cathode is nickel oxyhydroxide, and the anode is typically one of two types of metallic alloys. One such alloy is the Misch metal type, made up of rare earth alloys of lanthanum nickel (LaNi 5), known as the AB 5 class, and another is made up of titanium and zirconium, known as the AB 2 class. Substitutions of the Misch metal alloys can be made with cesium, neodymium, …
