Nickel metal hydride battery and lithium battery which good, have what distinction?
Ni-mh batteries Good. The differences between ni-MH batteries and lithium batteries are as follows:

1. Monomer voltage is different.The voltage of the lithium-ion battery is 3.7-4.2V, while the voltage of the ni-MH battery is only 1.2V. The electric capacity of a lithium-ion battery is equivalent to that of three ni-MH batteries in series.

2. Charging speed is different.Due to the active performance of lithium ion, it moves faster in the battery, so the charging current is larger and the charging speed is faster. A lithium ion battery can be filled in about 3 hours.However, the charging speed of nimH battery is very slow, and it takes about 1 day to fill up.

3. Different energy densities.Lithium ion battery has a high energy density. In the first batch of promotion catalogue in 2019, the energy density of electric vehicle power battery has reached above 160Wh/kg.Ni-mh batteries have a low energy density of only 40 ~ 70Wh /kg.Therefore, lithium-ion batteries are more powerful than nimH batteries at the same volume.
