Which is better nimh battery or li ion battery?

Which is better, li ion batteries or nimh batteries? This can not be concluded, the two have their own advantages, mainly depends on where you use in, like a mobile phone battery is more suitable for lithium batteries, but in the digital camera above, because the digital camera for the current demand is quite large, and the power consumption is also much larger than that of mobile phones, and the nimh battery in the high-current output part is slightly better.

Lithium batteries and nimh batteries have the following differences:

1, The single li ion battery voltage is 3.2 and 3.7v while a single nimh battery is 1.2V;

2. The lithium battery has no memory effect, and the nimh battery has a memory effect;

3, lithium battery does not contain heavy metals (cadmium);

4, There's no pollution for li ion battery manufacturing and useing with environmental protection;

5. The specific capacity of a lithium battery is high, and the specific capacity is the electric energy per unit volume and weight (wh);

6, The unit price of lithium batteries is high;

7, Li ion batteries have a long cycle life;

8, Li ion battery specifications are more specific than nimh batteries, versatility is not so strong, like the 5th (AA) Ni-MH battery and 7th (AAA) NiMH battery can use 5th (AA) carbon battery Or replace with AA alkaline batteries and No. 7 (AAA) carbon batteries or No. 7 (AAA) alkaline batteries.
