Nickel-metal hydride battery (NiMH or Ni-MH) is a type of rechargeable battery. Nickel-metal hydride (Ni-MH) batteries that use hydrogen storage alloys as the negative electrode material have drawn increased attention owing to their higher energy density both in terms of weight and volume, improved high-rate capability, and high tolerance to overdischarge.
NiMH batteries are used in over 95% of all HEVs, emerging EVs, and fuel cell EVs. It's a type of electrical battery which can be charged, discharged into electric cars and recharged many times, as opposed to a disposable or primary battery.
The major advantage of Nickel Metal Hybrid Battery is the safety compared to Li-ion batteries. Furthermore, NiMH batteries are preferred in industrial and consumer applications due to their design flexibility, environmental acceptability, low maintenance, high power and energy densities, and most importantly safety in both charge and discharge modes.
