The Compare of Lead-Acid Battery, NiMH Battery & Lithium-Ion Battery

There are three main types of battery in the cars, Lead-Acid battery, NiMH battery, and a lithium-ion battery. For electric cars, the lithium-ion battery is much better. You can see the advantages and disadvantages of the follows.

Lead-Acid Battery

Advantage:

The production process is much mature. The cost is lower than the other 2 types of batteries.

Disadvantage:

The electrolyte is not friendly with the environment. The working voltage & energy density are lower. The shape is limited. The weight is big.

Application:

The cost of lead-acid batteries is much lower than the type of batteries. But it limited by lower rating of charging & discharging for lower speed cars.

NiMH Battery

Advantage:

The working voltage & energy density is higher than the lead-acid battery. It can support over-charging & over-discharging.

Disadvantage:

Memory effect is higher and the cost is higher, too. The most shape is columniform, so that it can’t be used for the smaller applications.

Application:

Generally, it's used for consumer electronics products.

 

Lithium-ion Battery

Advantage:

The energy density and working voltage are much higher than the other 2 types of batteries. It's lighter without memory effect and friendly with environment. The battery life is long because of lower self-discharge. The shape is multiplex, so that it can be used for different applications.

Disadvantage:

The cost is the highest. The working temperature is limited. The technology of lithium-ion battery hasn't updated greatly.

Application:

It often used for 3C filed. More and more electric cars accept it.
