​

Nickel-metal-hydride batteries are rechargeable batteries whose performance lies between that of traditional nickel-cadmium batteries (Ni-Cd) and modern lithium-ion batteries (Li-ion). The active material of its positive electrode is nickel oxide hydroxide (NiOOH), and the active material of its negative electrode is Metal Hydride.

Advantages

High energy density

Its energy density is approximately 30-40% higher (volume energy density) or even higher (weight energy density) than that of its predecessor, the nickel-cadmium battery. This means that under the same volume or weight, it can store more electricity.

No memory effect

Compared with nickel-cadmium batteries, the memory effect of nickel-metal-hydride batteries is very slight and can almost be ignored. Users do not need to carry out a thorough "discharge - charge" cycle as they do with old-fashioned nickel-cadmium batteries to maintain battery capacity, making it more convenient to use.

Environmentally friendly

It does not contain highly toxic cadmium (Cd), causes less environmental pollution, is easier to dispose of after disposal, and is more in line with environmental protection regulations.

Good safety

Compared with lithium-ion batteries, the electrolyte of nickel-metal-hydride batteries is a water solution (potassium hydroxide), which is less flammable and explosive, has stronger resistance to overcharging and overdischarging, a wider operating temperature range, and higher safety.

Good high-current discharge performance

It can provide a large discharge current and is suitable for devices that require instantaneous high power output (such as remote control cars and power tools).
