The Difference Between Lithium Ion Batteries vs Lithium Iron Phosphate Batteries

Lithium iron phosphate (LiFePO4) batteries are a category or kind of lithium-ion batteries relatively new to the market. Nevertheless, both types are unique in their various aspects and excel in particular fields, industries, domains, and applications.
Let us compare the pros and cons of lithium-ion batteries and lithium iron phosphate batteries to find their differences in this article.

Lithium-ion batteries get composed primarily of lithium manganese dioxide or lithium cobalt dioxide as the material for the cathode. They have a secondary cell construction with multiple layers of lithium along with an electrolyte. Additionally, they have a graphite anode and a separator between the two charged electrodes.

Lithium iron phosphate batteries have a similar structure and construction to lithium-ion batteries. However, they come with lithium iron phosphate as the constituent material for the cathode and carbon for the anode.

Energy Density

Both lithium ion batteries and lithium iron phosphate batteries have considerably high energy densities. Nonetheless, the former excels more in this factor. In most cases, the energy density of lithium-ion batteries stands at about 150 Wh/kg to 200 Wh/kg. It is usually around 90 Wh/kg to 120 Wh/kg for lithium iron phosphate batteries.

Hence, lithium-ion batteries serve as the better choice for power-hungry applications that drain the battery capacity. They can also charge at a faster rate.


Lithium iron phosphate batteries possess superior and more significant chemical and thermal stability and come with other suitable and excellent safety features. They are non-combustible even when they experience extensive use, abuse, and mishandling during discharge and recharge. These batteries have a higher resistance to temperature fluctuations and thermal runaway. They can withstand high amounts of heat without melting or decomposing. In addition to these, lithium iron phosphate batteries are not composed of any toxic substances. Thus, they are entirely safe for use and application.

Although lithium-ion batteries also come with outstanding safety attributes and characteristics, they are not as beneficial as lithium iron phosphate batteries. It is because these batteries can suffer from overheating even under similar conditions of charging. They may also have hazardous materials which are not safe for exposure to humans.

Size and Weight

Lithium-ion batteries are considerably smaller and lightweight compared to lithium iron phosphate batteries. For this reason, they find applications in portable devices or appliances that need to get carried and lifted effortlessly.

Life Cycles

Lithium iron phosphate batteries come with and proffer around 1000 to 10,000 life cycles. It implies that they have a long lifespan and can get used for long periods. They can work perfectly and have a significant time difference between their charging times. It means that they do not need charging frequently.

For lithium-ion batteries, their high energy densities make them more unstable. Thus, they have a lower number of life cycles that stand at a number or numeric of around 500 to 1000.


When left unused, all batteries lose some of their charges due to some internal chemical reactions. These take place within their cells, resulting in an overall loss of capacity. In this regard, both lithium iron phosphate batteries and lithium-ion batteries provide good storage benefits that last for a long time.

On a comparative basis, lithium iron phosphate batteries have a shelf life of approximately 350 days, and lithium-ion batteries can last for roughly 300 days.
