Which kind of battery is better, Ni-MH battery or Li-ion battery? Both have their own advantages. If you do want
to know which one is better, let’s refer to the applications. For example, lithium ion battery is applied to mobile
phone batteries, but for digital cameras, Ni-MH battery is a better choice since cameras request high current and
large capacity consumption.
Below is the difference between Ni-MH battery and Li-ion battery:
a. Lithium ion battery voltage is 3.2V or 3.7V, while Ni-MH battery voltage is 1.2V;
b. Lithium ion battery has no memory effect, while Ni-MH battery has;
c. Lithium battery has more models, while Ni-MH battery has better generality; it can replace AA/AAA alkaline or
And below is the advantages of lithium ion battery:
a. Lithium ion battery contains no heavy metal element, such as cadmium, etc.;
b. Lithium battery is environmental friendly in manufacturing and application;
c. Lithium battery has high energy density and long cycle life.
