6 Lithium-ion Battery Types

From iron phosphate to nickel manganese cobalt oxide, there's more than one type of lithium-ion battery out there.

Lithium-ion batteries are essential to modern technology, powering smartphones, laptops, medical devices and even electric vehicles.

However, it is important to note that rather than using lithium metal for battery technologies, manufacturers commonly use lithium carbonate or lithium hydroxide. Moreover, there is more than one type of lithium-ion battery, and not all are created equal.

Several lithium compounds may be combined with a variety of other materials in order to create lithium-ion batteries. Below is an overview of six lithium-ion battery types, as well as their compositions and common uses. Read on to learn more about this exciting technology.

1. Lithium cobalt oxide

Also known as lithium cobalate or lithium-ion cobalt batteries, lithium cobalt oxide batteries are made from lithium carbonate and cobalt. Due to their very high capacity, these batteries are used for cellphones, laptops and electronic cameras. They have a cobalt oxide cathode and a graphite carbon anode; during discharge, lithium ions move from the anode to the cathode, with the flow reversing on charge.

This type of battery has some drawbacks, including a shorter lifespan and limited specific power. That means that devices that use these batteries require relatively frequent charging — as smartphone owners can attest. Additionally, Battery University notes these batteries are not as safe as other types.

2. Lithium manganese oxide

Lithium manganese oxide batteries are also commonly called lithium manganate or lithium-ion manganese batteries. They may also be referred to as li-manganese or spinel. The technology for this type of battery was discovered in the 1980s, with the first publication on the subject appearing in the Materials Research Bulletin in 1983. The first commercial lithium-ion cell made with a lithium manganese oxide as a cathode material was produced in 1996 by Moli Energy.

Lithium manganese oxide batteries are notable for their high thermal stability, and are also safer than other lithium-ion battery types. For this reason, they are often used in medical equipment and devices, but they may also be used in power tools, electric bikes and more. It is also possible to use lithium manganese oxide batteries to power laptops and electric powertrain cars.

3. Lithium iron phosphate

Lithium iron phosphate batteries, also known as li-phosphate batteries, use phosphate as a cathode. Li-phosphate batteries benefit from low resistance properties, which enhance their safety and thermal stability.

Other benefits include durability and a long life cycle — fully charged batteries can be stored with little change to the total lifespan of the battery’s charge. Li-phosphate batteries are often the most cost-effective option as well, when their long lifecycle is taken into consideration. However, the lower voltage of the li-phosphate battery means that it has less energy than other types of lithium batteries, as lower temperatures reduce performance.

Accordingly, these batteries are often used in electric motorcycles as well as other applications that need a long lifecycle and significant safety. Electric vehicles often use these batteries as well, according to Battery Space.

4. Lithium nickel manganese cobalt oxide

Also known as lithium manganese cobalt oxide or NMC batteries, lithium nickel manganese cobalt oxide batteries are made of several materials common in lithium-ion battery types. They include a cathode combination of nickel, manganese and cobalt.

Like other lithium-ion battery varieties, NMC batteries can have either a high specific energy or high specific power. They cannot, however, have both properties. This battery is most common in power tools and in powertrains for vehicles.

The cathode combination ratio is usually one-third nickel, one-third manganese and one-third cobalt, meaning that the raw material cost is lower than for other options, as cobalt on its own can be quite expensive. This battery is also commonly preferred for electric vehicles due to its very low self-heating rate.

5. Lithium nickel cobalt aluminum oxide

Lithium nickel cobalt aluminum oxide batteries are also called NCA batteries, and are becoming increasingly important in electric powertrains and in grid storage. NCA batteries are not common in the consumer industry, but are promising for the automotive industry. NCA batteries provide a high-energy option with a good lifespan, but they are not as safe as they could be and are quite costly. The Boston Consulting Group notes that NCA batteries must be accompanied in cars by safety measures that monitor the performance and behavior of these batteries to keep drivers secure.

The Argonne National Laboratory has conducted research into the potential of NCA batteries and the possible issues associated with them. Given the consistent use of NCA batteries in electric vehicles, it is possible that demand for these batteries will rise as electric vehicles become more common.

6. Lithium titanate

Finally, lithium titanate, also known as li-titanate, is a class of battery that allows for ever-increasing applications. The main advantage of the li-titanate battery is its remarkably fast recharge time, thanks to its advanced nanotechnology, writes Battery Space.

Currently, manufacturers of electric vehicles and bikes use li-titanate batteries, and there is a potential for this type of battery to be used in electric buses for public transportation. However, these batteries have lower inherent voltage, or lower energy density, than other varieties of lithium-ion battery, which can present issues with powering vehicles efficiently.

Still, the density of lithium titanate batteries is still higher than other non-lithium-ion batteries, which is a plus. Applications for these batteries can include military and aerospace uses, and they may also be used for storing wind and solar energy and creating smart grids. Furthermore, Battery Space suggests these batteries could also be used in system-critical backups for power systems.

    Why didn’t you include Li -S batteries? They seem to be much safer than some of the other choices.
