What are the advantages of ni-mh batteries over lithium-ion batteries?

Which is better, lithium-ion or nickel-metal hydride? This can not be concluded. Each has its own advantages. It mainly depends on what kind of electrical appliances you use. For example, a cell phone battery is more suitable for lithium-ion batteries, but when it comes to digital cameras, because digital cameras require a lot of current and consume much more power than mobile phones, nimh batteries are a little better at high current output.

The differences between lithium-ion and nickel-metal hydride batteries are as follows:

1. Single voltage of lithium battery 3.2 and 3.7 V, single NI-MH Battery 1.2 V. 2. Lithium battery has no memory effect, nickel-metal hydride battery has memory effect. 3. Lithium batteries do not contain heavy metals (cadmium) . 4. The manufacturing and using of lithium battery is environment-friendly and pollution-free. 5, lithium battery specific capacity is high, specific capacity is the unit volume, weight potential electrical energy (wh) . 6. Lithium-ion batteries cost more per unit charge. Lithium batteries have a long cycle life. 8. Lithium-ion batteries are more specialized than nimh batteries and are less versatile, batteries like No. 5(AA) NIMH and No. 7(AAA) NIMH can be replaced with No. 5(AA) carbon battery or No. 5(AA) alkaline battery and No. 7(AAA) carbon battery or No. 7(AAA) alkaline battery.
