Nickel metal hydride (NiMH) batteries are a type of rechargeable battery commonly used in consumer electronics and electric vehicles. They were developed as an alternative to the nickel-cadmium battery due to concerns over the toxicity of cadmium. NiMH batteries deliver comparable energy capacity to NiCd cells while avoiding the use of toxic materials. https://prachicmi.livepositively.com/nickel-metal-hydride-battery-an-environmentally-friendly-energy-storage-option/new=1
