The Pros And Cons Of Lithium Ion Batteries VS Nickel Metal Hydride Batteries

Lithium ion batteries and nickel-metal hydride (NiMH) batteries are two of the most commonly used batteries worldwide. However, some applications require either of the two due to several factors and parameters.

Let us discover the differences between lithium-ion batteries and nickel-metal hydride batteries through their unique pros and cons in this article.

Constituent Materials

The foremost and primary basis of a difference between lithium-ion batteries and nickel-metal hydride batteries lies in the materials their constituent materials. The former gets composed of carbon and lithium. On the other hand, the latter comes with hydrogen, nickel, and one other metal, generally titanium.

The highly reactive lithium stores the energy within the batteries for lithium-ion batteries. In the case of nickel-metal hydride batteries, hydrogen serves this role.


On a comparative basis, nickel-metal hydride batteries are less expensive than lithium-ion ones. It can get owed to factors like the arduous manufacturing process, laborious production, and so on.

However, research on the battery market suggests that due to increased demand for lithium ion batteries and more innovative development processes, the price may drop in the future.


Lithium-ion batteries are significantly lighter and smaller than nickel-metal hydride batteries. The heavier a battery pack is, the lower will be its energy density.

For this reason, lithium-ion batteries get used in hybrid cars where the battery power needs to overcome the vehicle’s inertia. They have to do so without any aid from the gasoline and acquire the maximum possible mileage.

Charging Time

Nickel metal hydride batteries and lithium-ion batteries have almost the same amount and quantity of power. However, the time taken for a charging and discharging cycle is substantially lower for the latter compared to the former. Thus, lithium-ion batteries are ready for use faster than the nickel hydride ones, even if they get put to charge together.

Additionally, lithium-ion batteries do not undergo or experience a powerful memory effect that can otherwise diminish their capacity.


Both lithium-ion batteries and nickel-metal hydride batteries have adequate durability that allows them to last for extended periods. Nevertheless, in this case, NiMH batteries have an advantage over Li-ion batteries.

While lithium ion batteries cannot handle extreme temperatures, especially the heat, nickel-metal hydride batteries can work perfectly in the same conditions.


Nickel metal hydride batteries are available in diverse shapes and sizes. This feature allows them to find applications in various sectors, fields, domains, and industries. Unlike most other batteries, they can fit and get used in cramped spaces.

On the other hand, lithium-ion batteries have a fixed set of sizes. They get manufactured only in this range. Thus, they have their applications pre-ordained.

Battery Charger

An enormous advantage of nickel-metal hydride batteries is that they can get charged using different chargers and not their unique own. It is not the case for lithium-ion batteries. Each variety of them has a particular charger that it must possess to get charged.

On account of this feature, it becomes exceedingly effortless and undemanding to charge the nickel-metal hydride batteries even if their charger gets lost or damaged.

Charge and Voltage Depletion

Lithium-ion batteries have an added advantage over nickel-metal hydride batteries. It is because they do not lose their charge or voltage over time. Thus, they can last for a long time and give an almost 100% work output for every use.
