2.Why lithium iron phosphate battery superior than lithium-ion battery?

Batteries are important for us to operate our essential electronic devices such as smartphones, computers, and other portable electronic devices. Not only for portable devices but also for electric vehicles, batteries are like their life. These electronic devices and vehicles are big and important investments. So, it is very important to ensure these devices' long life dependingends on their battery. These devices require batteries that can hold and store much energy. As these devices are portable, the batteries should be lightweight and easy to charge.

Lithium batteries are great choices for portable electronics and electric vehicles. There are several types of lithium batteries, such as Li-ion, Lithium iron phosphate, Lithium cobalt manganese, etc. However, Lithium ions and iron phosphate are the most popular items in this category. Because they are the best-performing batteries for the electronics and electric tools industry. Both batteries are rechargeable and have great output powers. Though both batteries share some similar attributes, Lithium iron phosphate is better in many aspects. Lithium iron phosphate wins the race in terms of high-energy density, lifespan, heat resistance, etc. 

In this article, I will tell you how Lithium iron phosphate batteries are better than Lithium-ion batteries. 

Why are lithium-iron phosphate batteries better?

Lithium-ion and Lithium iron phosphate (LiFePO4) batteries use lithium as an electrolyte. But the structure of cathodes and anode for performing electrolysis is different. And Lithium iron phosphate batteries are a step forward than other Li-ion batteries. Although lithium-ion batteries may have higher energy density and lower cost, LiFePO4 batteries are superior to them in many aspects. Let's know why Lithium iron phosphate is better than Li-ion batteries in the following-

Safety

Lithium, iron phosphate batteries ensure more safety to the user. These batteries are less prone to overheating. So, you don't have to worry about the risk of fire or explosion. This is because Lithium iron phosphate has lower energy density compared to lithium-ion batteries.

Longer lifespan

LiFePO4 batteries have a longer cycle life than other Li-ion batteries. So, you  can charge and discharge these batteries more times than traditional lithium-ion batteries before they degrade. Lithium iron phosphate has a stronger chemistry, ensuring a better chemical reaction. So the degradation caused by the electrolyte is less, and the battery gets a longer lifespan. 

Better performance at high temperatures

Lithium iron phosphate batteries can operate at higher temperatures than traditional lithium-ion batteries. It is because the battery uses phosphate as the cathode stand, which does not burn out in high heat. So a lithium iron phosphate battery has higher heat resistance than other Li-ion batteries.

Environmental friendly 

Lithium iron phosphate batteries are more environmentally friendly than traditional lithium-ion batteries. These batteries don't contain toxic materials like cobalt or nickel. Rather it uses phosphate and iron, which are good for soil and water. So when you dispose of these batteries, you don't have to worry about environmental pollution. 

These are the advantages that make Lithium iron phosphate batteries a better choice for many applications, such as electric vehicles. These batteries can be also used for renewable energy storage systems and backup power supplies.

What is the difference between lithium-ion and lithium-iron phosphate?

Lithium-ion (Li-ion) and lithium-iron phosphate (LiFePO4) batteries are both rechargeable batteries.  Both of the batteries use technologies that use lithium ions to store and release energy. However, there are some noticeable differences between them. 

The main difference between the two is in their chemical composition and performance characteristics. Li-ion batteries are typically lighter. They are more compact and have a higher energy density than LiFePO4 batteries. Li-ion batteries are used in products that need high power output. Some common applications in which Li-ion batteries are used are smartphones, laptops, and electric vehicles.

On the other hand, Lithium iron phosphate batteries are known for their safety, durability, and stability. They have a longer lifespan than Li-ion batteries. They can withstand high temperatures without the risk of catching fire or exploding. The chemical substances used in these batteries are iron, Lithium, and phosphate, which is good for the soil, and water. This makes them a popular choice for applications where safety and reliability are critical. Lithium iron phosphate batteries are mostly used for 

renewable energy storage- generators, backup power systems like IPS, and electric vehicles. 

Li-ion batteries are preferred for applications with high power and energy density. It means Li-ion batteries are suitable when you have to use the application for a longer time at a stretch. Lithium batteries are preferred for applications where safety, durability, and stability are more important factors.

Lithium Iron Phosphate VS Lithium-ion Batteries

Lithium iron phosphate (LiFePO4) and lithium-ion (Li-ion) batteries are both types of rechargeable lithium batteries, but they differ in several key aspects.

Chemistry

Lithium iron phosphate batteries use lithium iron phosphate as the cathode material and iron as the anode. Li-ion batteries use various cathode materials, such as lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), etc. However, both batteries use the same electrolyte- Li ions.

Energy Density

Lithium iron phosphate batteries have a lower energy density than Li-ion batteries. It means LiFePO4 batteries store less energy per unit of volume or weight. This makes them heavier and bulkier for a given capacity.

Cycle Life

Lithium iron phosphate batteries have a longer cycle life than Li-ion batteries LiFePO4 batteries can be charged and discharged more times before their capacity begins to degrade. At the same time, this charge and discharge rate is less in other Li-ion batteries.  This makes Lithium iron phosphate batteries more durable and longer-lasting.

Safety

Lithium and iron phosphate batteries are generally considered to be safer than Li-ion batteries. Li-on batteries can not perform well in extreme temperatures. LiFePO4 is less reactive to overheating and catching fire. This happens because LiFePO4 has stronger chemistry than Li-ion batteries. 

Cost

Lithium iron phosphate batteries are typically more expensive than Li-ion batteries. LiFePO4 batteries have higher manufacturing costs because they use expensive metals and substances. 

Conclusion

Both Lithium iron phosphate and Li-ion batteries are extensively used in several electronic and electric industries. Lithium iron phosphate batteries have some superiority in terms of safety and durability over Li-ion batteries. But they have different fields of application. So it is quite difficult to compare them.  However, you have to decide which one you will choose according to your device's preference.
