LiFePO4 Battery vs Ternary Lithium Battery: What’s Their Difference

LiFePO4 batteries and ternary lithium batteries are widely used in our life. They are commonly used in various applications such as solar power systems and UPS. Do you know anything about these two kinds of batteries?
In this blog, I will show you these two kinds of batteries and help you learn more about them.

What are LiFePO4 Battery & Ternary Lithium Battery?

LiFePO4, short for lithium iron phosphate battery, uses lithium iron phosphate as its positive electrode material.

And ternary lithium batteries have a positive electrode made of a combination of nickel, cobalt, and manganese/aluminum.

the Comparison between LiFePO4 Battery & Ternary Lithium Battery:

1.Safety

LiFePO4	Ternary Battery
stable and has great safety performance	inferior thermal stability performance
at 500-600℃ without releasing oxygen or causing violent combustion.	begin decomposing around 300℃, affecting thermal stability.

2.Energy Density

LiFePO4	Ternary Battery
140Wh/kg	240Wh/kg
Under the same weight, the energy density of the Ternary lithium battery is 1.7 times that of the LFP battery.

 

 

 

 

 

 3.Low-temperature Performance

LiFePO4	Ternary Battery
-20℃	-30℃
the discharge performance at low temperatures is less efficient	the discharge performance at low temperatures is good

4.Cycle Time

LiFePO4	Ternary Battery
roughly 3,500 cycles	roughly 2000 cycles
at 500-600℃ without releasing oxygen or causing violent combustion.	begin decomposing around 300℃, affecting thermal stability.

 

In summary, both battery types have their distinct advantages. If you need a battery with high safety, you can choose lithium iron phosphate batteries. If you want to use the battery at low temperatures, you can go for Ternary lithium batteries.
