What is the difference between NiMH and Lithium-ion batteries?

What is the difference between NiMH and Lithium-ion batteries?

NiMH (Nickel-Metal Hydride) batteries are known for their higher capacity and are often used in hybrid vehicles, while Lithium-ion batteries are lighter, have a higher energy density, and are commonly used in smartphones and laptops.

Which one lasts longer?

Lithium-ion batteries generally have a longer lifespan and can handle more charge cycles compared to NiMH batteries.

Are there any safety concerns with either type?

Yes, Lithium-ion batteries can pose safety risks if damaged or improperly charged, leading to overheating or fires. NiMH batteries are generally considered safer.

Which one should I choose for my electric vehicle?

For electric vehicles, Lithium-ion batteries are typically preferred due to their higher energy density and efficiency.

What about the environmental impact of both?

NiMH batteries are less harmful to the environment compared to Lithium-ion batteries, which contain toxic materials like cobalt. However, both types have recycling processes to mitigate their impact.
