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.
The difference between Ni-MH battery and Li-ion battery is below:
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 carbon battery.
The advantages of lithium ion battery is below:
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.
